Given numbers are 115, 661, 480, 557

The list of prime factors of all numbers are

Prime factors of 115 are 5 x 23

Prime factors of 661 are 661

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 557 are 557

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

Given numbers are 115, 661, 480, 557

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

Apply this formula for all numbers.

Step1:

LCM(115, 661) = 76015

GCD(115, 661) = ( 115 x 661 ) / 76015

= 115 / 661

= 115

Step2:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

Step3:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1

So, Greatest Common Divisor of 115, 661, 480, 557 is 1
