Given numbers are 618, 784, 531, 615

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 531 are 3 x 3 x 59

Prime factors of 615 are 3 x 5 x 41

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

Given numbers are 618, 784, 531, 615

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

Apply this formula for all numbers.

Step1:

LCM(618, 784) = 242256

GCD(618, 784) = ( 618 x 784 ) / 242256

= 618 / 784

= 618

Step2:

LCM(2, 531) = 1062

GCD(2, 531) = ( 2 x 531 ) / 1062

= 2 / 531

= 2

Step3:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

So, Greatest Common Divisor of 618, 784, 531, 615 is 1
