Given numbers are 57, 38, 28

The list of prime factors of all numbers are

Prime factors of 57 are 3 x 19

Prime factors of 38 are 2 x 19

Prime factors of 28 are 2 x 2 x 7

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

Given numbers are 57, 38, 28

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

Apply this formula for all numbers.

Step1:

LCM(57, 38) = 114

GCD(57, 38) = ( 57 x 38 ) / 114

= 57 / 38

= 57

Step2:

LCM(19, 28) = 532

GCD(19, 28) = ( 19 x 28 ) / 532

= 19 / 28

= 19

So, Greatest Common Divisor of 57, 38, 28 is 1
