Given numbers are 771, 436, 615, 621

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 436 are 2 x 2 x 109

Prime factors of 615 are 3 x 5 x 41

Prime factors of 621 are 3 x 3 x 3 x 23

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

Given numbers are 771, 436, 615, 621

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

Apply this formula for all numbers.

Step1:

LCM(771, 436) = 336156

GCD(771, 436) = ( 771 x 436 ) / 336156

= 771 / 436

= 771

Step2:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 771, 436, 615, 621 is 1
