Given numbers are 810, 356, 615, 130

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 356 are 2 x 2 x 89

Prime factors of 615 are 3 x 5 x 41

Prime factors of 130 are 2 x 5 x 13

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

Given numbers are 810, 356, 615, 130

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

Apply this formula for all numbers.

Step1:

LCM(810, 356) = 144180

GCD(810, 356) = ( 810 x 356 ) / 144180

= 810 / 356

= 810

Step2:

LCM(2, 615) = 1230

GCD(2, 615) = ( 2 x 615 ) / 1230

= 2 / 615

= 2

Step3:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

So, Greatest Common Divisor of 810, 356, 615, 130 is 1
