Given numbers are 777, 668, 220, 384

The list of prime factors of all numbers are

Prime factors of 777 are 3 x 7 x 37

Prime factors of 668 are 2 x 2 x 167

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 384 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 777, 668, 220, 384

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

Apply this formula for all numbers.

Step1:

LCM(777, 668) = 519036

GCD(777, 668) = ( 777 x 668 ) / 519036

= 777 / 668

= 777

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 384) = 384

GCD(1, 384) = ( 1 x 384 ) / 384

= 1 / 384

= 1

So, Greatest Common Divisor of 777, 668, 220, 384 is 1
