Given numbers are 730, 490, 656, 975

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

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

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 975 are 3 x 5 x 5 x 13

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

Given numbers are 730, 490, 656, 975

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

Apply this formula for all numbers.

Step1:

LCM(730, 490) = 35770

GCD(730, 490) = ( 730 x 490 ) / 35770

= 730 / 490

= 730

Step2:

LCM(10, 656) = 3280

GCD(10, 656) = ( 10 x 656 ) / 3280

= 10 / 656

= 10

Step3:

LCM(2, 975) = 1950

GCD(2, 975) = ( 2 x 975 ) / 1950

= 2 / 975

= 2

So, Greatest Common Divisor of 730, 490, 656, 975 is 1
