Given numbers are 132, 544, 621, 643

The list of prime factors of all numbers are

Prime factors of 132 are 2 x 2 x 3 x 11

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

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

Prime factors of 643 are 643

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

Given numbers are 132, 544, 621, 643

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

Apply this formula for all numbers.

Step1:

LCM(132, 544) = 17952

GCD(132, 544) = ( 132 x 544 ) / 17952

= 132 / 544

= 132

Step2:

LCM(4, 621) = 2484

GCD(4, 621) = ( 4 x 621 ) / 2484

= 4 / 621

= 4

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 132, 544, 621, 643 is 1
