Given numbers are 515, 870, 974, 438

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 974 are 2 x 487

Prime factors of 438 are 2 x 3 x 73

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

Given numbers are 515, 870, 974, 438

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

Apply this formula for all numbers.

Step1:

LCM(515, 870) = 89610

GCD(515, 870) = ( 515 x 870 ) / 89610

= 515 / 870

= 515

Step2:

LCM(5, 974) = 4870

GCD(5, 974) = ( 5 x 974 ) / 4870

= 5 / 974

= 5

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 515, 870, 974, 438 is 1
