Given numbers are 415, 764, 130, 421

The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

Prime factors of 764 are 2 x 2 x 191

Prime factors of 130 are 2 x 5 x 13

Prime factors of 421 are 421

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

Given numbers are 415, 764, 130, 421

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

Apply this formula for all numbers.

Step1:

LCM(415, 764) = 317060

GCD(415, 764) = ( 415 x 764 ) / 317060

= 415 / 764

= 415

Step2:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 415, 764, 130, 421 is 1
