Given numbers are 122, 620, 625, 181

The list of prime factors of all numbers are

Prime factors of 122 are 2 x 61

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 625 are 5 x 5 x 5 x 5

Prime factors of 181 are 181

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

Given numbers are 122, 620, 625, 181

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

Apply this formula for all numbers.

Step1:

LCM(122, 620) = 37820

GCD(122, 620) = ( 122 x 620 ) / 37820

= 122 / 620

= 122

Step2:

LCM(2, 625) = 1250

GCD(2, 625) = ( 2 x 625 ) / 1250

= 2 / 625

= 2

Step3:

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

= 1 / 181

= 1

So, Greatest Common Divisor of 122, 620, 625, 181 is 1
