Given numbers are 840, 621, 264, 172

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Prime factors of 264 are 2 x 2 x 2 x 3 x 11

Prime factors of 172 are 2 x 2 x 43

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

Given numbers are 840, 621, 264, 172

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

Apply this formula for all numbers.

Step1:

LCM(840, 621) = 173880

GCD(840, 621) = ( 840 x 621 ) / 173880

= 840 / 621

= 840

Step2:

LCM(3, 264) = 264

GCD(3, 264) = ( 3 x 264 ) / 264

= 3 / 264

= 3

Step3:

LCM(3, 172) = 516

GCD(3, 172) = ( 3 x 172 ) / 516

= 3 / 172

= 3

So, Greatest Common Divisor of 840, 621, 264, 172 is 1
