Given numbers are 515, 461, 623, 490

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 461 are 461

Prime factors of 623 are 7 x 89

Prime factors of 490 are 2 x 5 x 7 x 7

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

Given numbers are 515, 461, 623, 490

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

Apply this formula for all numbers.

Step1:

LCM(515, 461) = 237415

GCD(515, 461) = ( 515 x 461 ) / 237415

= 515 / 461

= 515

Step2:

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

= 1 / 623

= 1

Step3:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

So, Greatest Common Divisor of 515, 461, 623, 490 is 1
