Given numbers are 147, 252, 621, 764

The list of prime factors of all numbers are

Prime factors of 147 are 3 x 7 x 7

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

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

Prime factors of 764 are 2 x 2 x 191

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

Given numbers are 147, 252, 621, 764

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

Apply this formula for all numbers.

Step1:

LCM(147, 252) = 1764

GCD(147, 252) = ( 147 x 252 ) / 1764

= 147 / 252

= 147

Step2:

LCM(21, 621) = 4347

GCD(21, 621) = ( 21 x 621 ) / 4347

= 21 / 621

= 21

Step3:

LCM(3, 764) = 2292

GCD(3, 764) = ( 3 x 764 ) / 2292

= 3 / 764

= 3

So, Greatest Common Divisor of 147, 252, 621, 764 is 1
