GCD of numbers is the greatest common divisor

So, the GCD (57, 54, 74, 61) = 1.

Given numbers are 57, 54, 74, 61

The list of prime factors of all numbers are

Prime factors of 57 are 3 x 19

Prime factors of 54 are 2 x 3 x 3 x 3

Prime factors of 74 are 2 x 37

Prime factors of 61 are 61

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

Given numbers are 57, 54, 74, 61

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

Apply this formula for all numbers.

Step1:

LCM(57, 54) = 1026

GCD(57, 54) = ( 57 x 54 ) / 1026

= 57 / 54

= 57

Step2:

LCM(3, 74) = 222

GCD(3, 74) = ( 3 x 74 ) / 222

= 3 / 74

= 3

Step3:

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

= 1 / 61

= 1

So, Greatest Common Divisor of 57, 54, 74, 61 is 1
