8 times 17 is 136 — with the shortcut, the division facts and a drill to make it stick
8 × 17 = 136. That is the short answer, and it is the same answer whichever way round you write the two numbers. Below is where 136 comes from, the shortcut that gets you there without counting, the division facts that travel with it, and the fastest way to move it from "I can work it out" to "I just know it".
8 × 17 = 136. Said out loud in the way most classrooms say it: Eight seventeens are one hundred and thirty-six.
17 + 17 + 17 + 17 + 17 + 17 + 17 + 17 = 136 — that is eight seventeens added together.
Written the other way round the answer does not change. 17 × 8 = 136 as well, because multiplication is commutative — the order of the two factors never affects the product. That halves how many facts you actually have to learn: get 8 × 17 and you have 17 × 8 for free.
Double three times. 17 → 34 → 68 → 136.
Because one of the factors is even, the answer has to be even. 136 is, so the parity check passes.
Every multiplication fact comes with a division fact on its back. These four all say the same thing about 8, 17 and 136: 8 × 17 = 136; 17 × 8 = 136; 136 ÷ 8 = 17; 136 ÷ 17 = 8.
Learning them as one family rather than four separate things is the single biggest shortcut in times-table practice. If you can answer "136 divided by 8" as fast as you can answer "8 times 17", the fact is genuinely learned rather than just recognised.
In the 8 times table, 136 is the seventeenth step: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, 136.
In the 17 times table it is the eighth step instead: 17, 34, 51, 68, 85, 102, 119, 136, 153, 170, 187, 204.
Seeing the same number arrive from two directions is what makes it stick. 136 is a landmark in both rows, so whichever table you are drilling you meet it again.
8 × 16 = 128, 8 × 18 = 144, 7 × 17 = 119, 9 × 17 = 153. Those are the answers people most often give by accident when they are a beat too quick.
The gap between neighbours is worth knowing on its own: each extra eight adds 8 to the running total, and each extra seventeen adds 17. So if 8 × 17 = 136 is solid, you can reach 8 × 18 by adding 8 rather than starting again.
Recognising a fact and recalling it under time pressure are different skills. A fact you can work out in four seconds still costs you four seconds every time it appears inside a longer calculation.
Short daily bursts beat long sessions: a 60-second drill every day will fix a table faster than one twenty-minute sitting a week. Mix the fact you are learning in among ones you already know so recall is being tested, not the order of a list.
8 times 17 is 136. In words, eight seventeens are one hundred and thirty-six.
17 times 8 is also 136. Swapping the two factors never changes the answer, so 17 × 8 and 8 × 17 both come to 136.
136 ÷ 8 = 17, because 8 × 17 = 136. The matching fact is 136 ÷ 17 = 8.
Double three times. 17 → 34 → 68 → 136.
Yes. 136 is the seventeenth number in the 8 times table, and the eighth number in the 17 times table.
