5. Evaluate correct up to two places of decimal.​

Answer 1

Answer:

Find the greatest common divisor:

gcd(16, 20, 36)

Find the divisors of each integer and select the largest element they have in common:

The divisors of 16 are:

1, 2, 4, 8, 16

The divisors of 20 are:

1, 2, 4, 5, 10, 20

The divisors of 36 are:

1, 2, 3, 4, 6, 9, 12, 18, 36

The largest number common to all divisor lists is 4:

divisors of 16: 1, 2, 4, 8, 16

divisors of 20: 1, 2, 4, 5, 10, 20

divisors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
