Given numbers are 681, 972, 515, 185

The list of prime factors of all numbers are

Prime factors of 681 are 3 x 227

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 515 are 5 x 103

Prime factors of 185 are 5 x 37

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

Given numbers are 681, 972, 515, 185

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

Apply this formula for all numbers.

Step1:

LCM(681, 972) = 220644

GCD(681, 972) = ( 681 x 972 ) / 220644

= 681 / 972

= 681

Step2:

LCM(3, 515) = 1545

GCD(3, 515) = ( 3 x 515 ) / 1545

= 3 / 515

= 3

Step3:

LCM(1, 185) = 185

GCD(1, 185) = ( 1 x 185 ) / 185

= 1 / 185

= 1

So, Greatest Common Divisor of 681, 972, 515, 185 is 1
