Given numbers are 956, 558, 561, 407

The list of prime factors of all numbers are

Prime factors of 956 are 2 x 2 x 239

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 561 are 3 x 11 x 17

Prime factors of 407 are 11 x 37

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

Given numbers are 956, 558, 561, 407

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

Apply this formula for all numbers.

Step1:

LCM(956, 558) = 266724

GCD(956, 558) = ( 956 x 558 ) / 266724

= 956 / 558

= 956

Step2:

LCM(2, 561) = 1122

GCD(2, 561) = ( 2 x 561 ) / 1122

= 2 / 561

= 2

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 956, 558, 561, 407 is 1
