Given numbers are 515, 840, 616, 538

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

Prime factors of 538 are 2 x 269

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

Given numbers are 515, 840, 616, 538

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

Apply this formula for all numbers.

Step1:

LCM(515, 840) = 86520

GCD(515, 840) = ( 515 x 840 ) / 86520

= 515 / 840

= 515

Step2:

LCM(5, 616) = 3080

GCD(5, 616) = ( 5 x 616 ) / 3080

= 5 / 616

= 5

Step3:

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

= 1 / 538

= 1

So, Greatest Common Divisor of 515, 840, 616, 538 is 1
