Given numbers are 669, 688, 980, 730

The list of prime factors of all numbers are

Prime factors of 669 are 3 x 223

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 730 are 2 x 5 x 73

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

Given numbers are 669, 688, 980, 730

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

Apply this formula for all numbers.

Step1:

LCM(669, 688) = 460272

GCD(669, 688) = ( 669 x 688 ) / 460272

= 669 / 688

= 669

Step2:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

Step3:

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

= 1 / 730

= 1

So, Greatest Common Divisor of 669, 688, 980, 730 is 1
