Given numbers are 515, 612, 778, 218

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 778 are 2 x 389

Prime factors of 218 are 2 x 109

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

Given numbers are 515, 612, 778, 218

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

Apply this formula for all numbers.

Step1:

LCM(515, 612) = 315180

GCD(515, 612) = ( 515 x 612 ) / 315180

= 515 / 612

= 515

Step2:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 515, 612, 778, 218 is 1
