Given numbers are 770, 648, 764, 957

The list of prime factors of all numbers are

Prime factors of 770 are 2 x 5 x 7 x 11

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

Prime factors of 764 are 2 x 2 x 191

Prime factors of 957 are 3 x 11 x 29

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

Given numbers are 770, 648, 764, 957

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

Apply this formula for all numbers.

Step1:

LCM(770, 648) = 249480

GCD(770, 648) = ( 770 x 648 ) / 249480

= 770 / 648

= 770

Step2:

LCM(2, 764) = 764

GCD(2, 764) = ( 2 x 764 ) / 764

= 2 / 764

= 2

Step3:

LCM(2, 957) = 1914

GCD(2, 957) = ( 2 x 957 ) / 1914

= 2 / 957

= 2

So, Greatest Common Divisor of 770, 648, 764, 957 is 1
