If the result is divisible by 13, then so was the first number. For Example : 50661 5066 + 4 = 5070 507 + 0 = 507 50 + 28 = 78 and 78 is 6 × 13, so 50661 is divisible by 13. Please help me!!! WebIs 560 divisible by 8? 560 / 8 = 70 Yes! So if 560 is divisible by 8, then so is 4560! Because 4000 is a multiple of 1000. And 1000 is a multiple of 100. And we have already established that 100 is divisible by 4. Then so is 1000 and 4000. 4000 = 1000 + 1000 + 1000 + 1000 But 570 is NOT a multiple of 1000! 570 < 1000 fairchild hiller fh-27 j
