Given numbers are 122, 605, 761, 720

The list of prime factors of all numbers are

Prime factors of 122 are 2 x 61

Prime factors of 605 are 5 x 11 x 11

Prime factors of 761 are 761

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 122, 605, 761, 720

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

Apply this formula for all numbers.

Step1:

LCM(122, 605) = 73810

GCD(122, 605) = ( 122 x 605 ) / 73810

= 122 / 605

= 122

Step2:

LCM(1, 761) = 761

GCD(1, 761) = ( 1 x 761 ) / 761

= 1 / 761

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 122, 605, 761, 720 is 1
