2 x 20 = 40

Answer:

2 x 2 x 2 x 5

Step-by-step explanation:

40 = 4 * 10

Factor

      = 2*2   * 5*2

Putting them in order from smallest to largest

      = 2 *2 * 2 *5

2 x 5  = 10

2 x 20 =40  Factor of 40

2 x 2 x 2 x 5 = 40   Prime factorization of 40

2 x 2 x 4 x 5 = 80

I think you are looking for the prime factorization of 40, which means breaking the numbers down into primes.
