Given numbers are 830, 615, 138, 876

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 615 are 3 x 5 x 41

Prime factors of 138 are 2 x 3 x 23

Prime factors of 876 are 2 x 2 x 3 x 73

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

Given numbers are 830, 615, 138, 876

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

Apply this formula for all numbers.

Step1:

LCM(830, 615) = 102090

GCD(830, 615) = ( 830 x 615 ) / 102090

= 830 / 615

= 830

Step2:

LCM(5, 138) = 690

GCD(5, 138) = ( 5 x 138 ) / 690

= 5 / 138

= 5

Step3:

LCM(1, 876) = 876

GCD(1, 876) = ( 1 x 876 ) / 876

= 1 / 876

= 1

So, Greatest Common Divisor of 830, 615, 138, 876 is 1
