Given numbers are 764, 638, 553, 450

The list of prime factors of all numbers are

Prime factors of 764 are 2 x 2 x 191

Prime factors of 638 are 2 x 11 x 29

Prime factors of 553 are 7 x 79

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

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

Given numbers are 764, 638, 553, 450

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

Apply this formula for all numbers.

Step1:

LCM(764, 638) = 243716

GCD(764, 638) = ( 764 x 638 ) / 243716

= 764 / 638

= 764

Step2:

LCM(2, 553) = 1106

GCD(2, 553) = ( 2 x 553 ) / 1106

= 2 / 553

= 2

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 764, 638, 553, 450 is 1
