Given numbers are 844, 405, 126, 660

The list of prime factors of all numbers are

Prime factors of 844 are 2 x 2 x 211

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 844, 405, 126, 660

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

Apply this formula for all numbers.

Step1:

LCM(844, 405) = 341820

GCD(844, 405) = ( 844 x 405 ) / 341820

= 844 / 405

= 844

Step2:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 844, 405, 126, 660 is 1
