Given numbers are 177, 920, 648, 404

The list of prime factors of all numbers are

Prime factors of 177 are 3 x 59

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 404 are 2 x 2 x 101

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

Given numbers are 177, 920, 648, 404

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

Apply this formula for all numbers.

Step1:

LCM(177, 920) = 162840

GCD(177, 920) = ( 177 x 920 ) / 162840

= 177 / 920

= 177

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

So, Greatest Common Divisor of 177, 920, 648, 404 is 1
