Given numbers are 780, 776, 78, 869

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 776 are 2 x 2 x 2 x 97

Prime factors of 78 are 2 x 3 x 13

Prime factors of 869 are 11 x 79

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

Given numbers are 780, 776, 78, 869

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

Apply this formula for all numbers.

Step1:

LCM(780, 776) = 151320

GCD(780, 776) = ( 780 x 776 ) / 151320

= 780 / 776

= 780

Step2:

LCM(4, 78) = 156

GCD(4, 78) = ( 4 x 78 ) / 156

= 4 / 78

= 4

Step3:

LCM(2, 869) = 1738

GCD(2, 869) = ( 2 x 869 ) / 1738

= 2 / 869

= 2

So, Greatest Common Divisor of 780, 776, 78, 869 is 1
