Given numbers are 720, 316, 891, 778

The list of prime factors of all numbers are

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 316 are 2 x 2 x 79

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

Prime factors of 778 are 2 x 389

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

Given numbers are 720, 316, 891, 778

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

Apply this formula for all numbers.

Step1:

LCM(720, 316) = 56880

GCD(720, 316) = ( 720 x 316 ) / 56880

= 720 / 316

= 720

Step2:

LCM(4, 891) = 3564

GCD(4, 891) = ( 4 x 891 ) / 3564

= 4 / 891

= 4

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 720, 316, 891, 778 is 1
