Given numbers are 771, 177, 365, 128

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 177 are 3 x 59

Prime factors of 365 are 5 x 73

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 771, 177, 365, 128

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

Apply this formula for all numbers.

Step1:

LCM(771, 177) = 45489

GCD(771, 177) = ( 771 x 177 ) / 45489

= 771 / 177

= 771

Step2:

LCM(3, 365) = 1095

GCD(3, 365) = ( 3 x 365 ) / 1095

= 3 / 365

= 3

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 771, 177, 365, 128 is 1
