Given numbers are 920, 161, 610, 515

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 161 are 7 x 23

Prime factors of 610 are 2 x 5 x 61

Prime factors of 515 are 5 x 103

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

Given numbers are 920, 161, 610, 515

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

Apply this formula for all numbers.

Step1:

LCM(920, 161) = 6440

GCD(920, 161) = ( 920 x 161 ) / 6440

= 920 / 161

= 920

Step2:

LCM(23, 610) = 14030

GCD(23, 610) = ( 23 x 610 ) / 14030

= 23 / 610

= 23

Step3:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 920, 161, 610, 515 is 1
