Question

Write each number as a product of prime numbers: 120, 640, and 2520.

Answer 1

Prime divisor on the right
120 | 2
60 | 2
30 | 2
15 | 3
5 | 5
1
So, 120=2*2*2*3*5

Answer 2

Verify the following result using @Valdas's method shown above.\[\{120,640,2520\}\to \{(2{}^{\wedge}3,3,5),(2{}^{\wedge}7,5),\{2{}^{\wedge}3,3{}^{\wedge}2,5,7\}\} \]
