Given numbers are 920, 668, 915, 161

The list of prime factors of all numbers are

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 668 are 2 x 2 x 167

Prime factors of 915 are 3 x 5 x 61

Prime factors of 161 are 7 x 23

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

Given numbers are 920, 668, 915, 161

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

Apply this formula for all numbers.

Step1:

LCM(920, 668) = 153640

GCD(920, 668) = ( 920 x 668 ) / 153640

= 920 / 668

= 920

Step2:

LCM(4, 915) = 3660

GCD(4, 915) = ( 4 x 915 ) / 3660

= 4 / 915

= 4

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 920, 668, 915, 161 is 1
