Given numbers are 770, 255, 951, 815

The list of prime factors of all numbers are

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

Prime factors of 255 are 3 x 5 x 17

Prime factors of 951 are 3 x 317

Prime factors of 815 are 5 x 163

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

Given numbers are 770, 255, 951, 815

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

Apply this formula for all numbers.

Step1:

LCM(770, 255) = 39270

GCD(770, 255) = ( 770 x 255 ) / 39270

= 770 / 255

= 770

Step2:

LCM(5, 951) = 4755

GCD(5, 951) = ( 5 x 951 ) / 4755

= 5 / 951

= 5

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 770, 255, 951, 815 is 1
