Given numbers are 777, 157, 630, 770

The list of prime factors of all numbers are

Prime factors of 777 are 3 x 7 x 37

Prime factors of 157 are 157

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

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

Given numbers are 777, 157, 630, 770

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

Apply this formula for all numbers.

Step1:

LCM(777, 157) = 121989

GCD(777, 157) = ( 777 x 157 ) / 121989

= 777 / 157

= 777

Step2:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 777, 157, 630, 770 is 1
