Given numbers are 646, 915, 305, 880

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 915 are 3 x 5 x 61

Prime factors of 305 are 5 x 61

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

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

Given numbers are 646, 915, 305, 880

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

Apply this formula for all numbers.

Step1:

LCM(646, 915) = 591090

GCD(646, 915) = ( 646 x 915 ) / 591090

= 646 / 915

= 646

Step2:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

Step3:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

So, Greatest Common Divisor of 646, 915, 305, 880 is 1
