Given numbers are 122, 515, 416, 661

The list of prime factors of all numbers are

Prime factors of 122 are 2 x 61

Prime factors of 515 are 5 x 103

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 661 are 661

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

Given numbers are 122, 515, 416, 661

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

Apply this formula for all numbers.

Step1:

LCM(122, 515) = 62830

GCD(122, 515) = ( 122 x 515 ) / 62830

= 122 / 515

= 122

Step2:

LCM(1, 416) = 416

GCD(1, 416) = ( 1 x 416 ) / 416

= 1 / 416

= 1

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 122, 515, 416, 661 is 1
