Given numbers are 97, 15, 20

The list of prime factors of all numbers are

Prime factors of 97 are 97

Prime factors of 15 are 3 x 5

Prime factors of 20 are 2 x 2 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 97, 15, 20

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(97, 15) = 1455

GCD(97, 15) = ( 97 x 15 ) / 1455

= 97 / 15

= 97

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

So, Greatest Common Divisor of 97, 15, 20 is 1
