Given numbers are 775, 756, 989, 479

The list of prime factors of all numbers are

Prime factors of 775 are 5 x 5 x 31

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 989 are 23 x 43

Prime factors of 479 are 479

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

Given numbers are 775, 756, 989, 479

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

Apply this formula for all numbers.

Step1:

LCM(775, 756) = 585900

GCD(775, 756) = ( 775 x 756 ) / 585900

= 775 / 756

= 775

Step2:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

Step3:

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

= 1 / 479

= 1

So, Greatest Common Divisor of 775, 756, 989, 479 is 1
