Given numbers are 615, 416, 257, 219

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 257 are 257

Prime factors of 219 are 3 x 73

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

Given numbers are 615, 416, 257, 219

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

Apply this formula for all numbers.

Step1:

LCM(615, 416) = 255840

GCD(615, 416) = ( 615 x 416 ) / 255840

= 615 / 416

= 615

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 219) = 219

GCD(1, 219) = ( 1 x 219 ) / 219

= 1 / 219

= 1

So, Greatest Common Divisor of 615, 416, 257, 219 is 1
