Given numbers are 812, 644, 159, 121

The list of prime factors of all numbers are

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 159 are 3 x 53

Prime factors of 121 are 11 x 11

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

Given numbers are 812, 644, 159, 121

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

Apply this formula for all numbers.

Step1:

LCM(812, 644) = 18676

GCD(812, 644) = ( 812 x 644 ) / 18676

= 812 / 644

= 812

Step2:

LCM(28, 159) = 4452

GCD(28, 159) = ( 28 x 159 ) / 4452

= 28 / 159

= 28

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 812, 644, 159, 121 is 1
