Given numbers are 316, 298, 821, 780

The list of prime factors of all numbers are

Prime factors of 316 are 2 x 2 x 79

Prime factors of 298 are 2 x 149

Prime factors of 821 are 821

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

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

Given numbers are 316, 298, 821, 780

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

Apply this formula for all numbers.

Step1:

LCM(316, 298) = 47084

GCD(316, 298) = ( 316 x 298 ) / 47084

= 316 / 298

= 316

Step2:

LCM(2, 821) = 1642

GCD(2, 821) = ( 2 x 821 ) / 1642

= 2 / 821

= 2

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 316, 298, 821, 780 is 1
