Given numbers are 770, 644, 142, 813

The list of prime factors of all numbers are

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

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 142 are 2 x 71

Prime factors of 813 are 3 x 271

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

Given numbers are 770, 644, 142, 813

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

Apply this formula for all numbers.

Step1:

LCM(770, 644) = 35420

GCD(770, 644) = ( 770 x 644 ) / 35420

= 770 / 644

= 770

Step2:

LCM(14, 142) = 994

GCD(14, 142) = ( 14 x 142 ) / 994

= 14 / 142

= 14

Step3:

LCM(2, 813) = 1626

GCD(2, 813) = ( 2 x 813 ) / 1626

= 2 / 813

= 2

So, Greatest Common Divisor of 770, 644, 142, 813 is 1
