Given numbers are 120, 643, 121, 844

The list of prime factors of all numbers are

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 643 are 643

Prime factors of 121 are 11 x 11

Prime factors of 844 are 2 x 2 x 211

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

Given numbers are 120, 643, 121, 844

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

Apply this formula for all numbers.

Step1:

LCM(120, 643) = 77160

GCD(120, 643) = ( 120 x 643 ) / 77160

= 120 / 643

= 120

Step2:

LCM(1, 121) = 121

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

= 1 / 121

= 1

Step3:

LCM(1, 844) = 844

GCD(1, 844) = ( 1 x 844 ) / 844

= 1 / 844

= 1

So, Greatest Common Divisor of 120, 643, 121, 844 is 1
