____________ X__________= 1,236

Answer 1

first answer is 21 X 68
second answer is 18 X 26

Answer 2

1428 = 2*2*3*7*17

we need to choose the 2 numbers from 1,2,6,8 from these factors

One set would be 3 * 7 = 21 and 2*2*17 = 68
so first one would be 21 * 68 = 1428

Part 2

1236 = 2 * 618

answer 2 * 618
