Given numbers are 730, 684, 217, 663

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 217 are 7 x 31

Prime factors of 663 are 3 x 13 x 17

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

Given numbers are 730, 684, 217, 663

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

Apply this formula for all numbers.

Step1:

LCM(730, 684) = 249660

GCD(730, 684) = ( 730 x 684 ) / 249660

= 730 / 684

= 730

Step2:

LCM(2, 217) = 434

GCD(2, 217) = ( 2 x 217 ) / 434

= 2 / 217

= 2

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 730, 684, 217, 663 is 1
