Given numbers are 642, 495, 456, 662

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 662 are 2 x 331

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

Given numbers are 642, 495, 456, 662

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

Apply this formula for all numbers.

Step1:

LCM(642, 495) = 105930

GCD(642, 495) = ( 642 x 495 ) / 105930

= 642 / 495

= 642

Step2:

LCM(3, 456) = 456

GCD(3, 456) = ( 3 x 456 ) / 456

= 3 / 456

= 3

Step3:

LCM(3, 662) = 1986

GCD(3, 662) = ( 3 x 662 ) / 1986

= 3 / 662

= 3

So, Greatest Common Divisor of 642, 495, 456, 662 is 1
