Given numbers are 717, 220, 61, 401

The list of prime factors of all numbers are

Prime factors of 717 are 3 x 239

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 61 are 61

Prime factors of 401 are 401

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

Given numbers are 717, 220, 61, 401

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

Apply this formula for all numbers.

Step1:

LCM(717, 220) = 157740

GCD(717, 220) = ( 717 x 220 ) / 157740

= 717 / 220

= 717

Step2:

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

= 1 / 61

= 1

Step3:

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

= 1 / 401

= 1

So, Greatest Common Divisor of 717, 220, 61, 401 is 1
