Given numbers are 621, 156, 23, 133

The list of prime factors of all numbers are

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

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 23 are 23

Prime factors of 133 are 7 x 19

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

Given numbers are 621, 156, 23, 133

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

Apply this formula for all numbers.

Step1:

LCM(621, 156) = 32292

GCD(621, 156) = ( 621 x 156 ) / 32292

= 621 / 156

= 621

Step2:

LCM(3, 23) = 69

GCD(3, 23) = ( 3 x 23 ) / 69

= 3 / 23

= 3

Step3:

LCM(1, 133) = 133

GCD(1, 133) = ( 1 x 133 ) / 133

= 1 / 133

= 1

So, Greatest Common Divisor of 621, 156, 23, 133 is 1
