Given numbers are 756, 730, 390, 261

The list of prime factors of all numbers are

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 730 are 2 x 5 x 73

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 756, 730, 390, 261

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

Apply this formula for all numbers.

Step1:

LCM(756, 730) = 275940

GCD(756, 730) = ( 756 x 730 ) / 275940

= 756 / 730

= 756

Step2:

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

= 2 / 390

= 2

Step3:

LCM(2, 261) = 522

GCD(2, 261) = ( 2 x 261 ) / 522

= 2 / 261

= 2

So, Greatest Common Divisor of 756, 730, 390, 261 is 1
