Given numbers are 615, 238, 978, 784

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 238 are 2 x 7 x 17

Prime factors of 978 are 2 x 3 x 163

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

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

Given numbers are 615, 238, 978, 784

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

Apply this formula for all numbers.

Step1:

LCM(615, 238) = 146370

GCD(615, 238) = ( 615 x 238 ) / 146370

= 615 / 238

= 615

Step2:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 615, 238, 978, 784 is 1
