Given numbers are 770, 760, 869, 638

The list of prime factors of all numbers are

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

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

Prime factors of 869 are 11 x 79

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 770, 760, 869, 638

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

Apply this formula for all numbers.

Step1:

LCM(770, 760) = 58520

GCD(770, 760) = ( 770 x 760 ) / 58520

= 770 / 760

= 770

Step2:

LCM(10, 869) = 8690

GCD(10, 869) = ( 10 x 869 ) / 8690

= 10 / 869

= 10

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 770, 760, 869, 638 is 1
