Given numbers are 660, 209, 137, 723

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 209 are 11 x 19

Prime factors of 137 are 137

Prime factors of 723 are 3 x 241

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

Given numbers are 660, 209, 137, 723

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

Apply this formula for all numbers.

Step1:

LCM(660, 209) = 12540

GCD(660, 209) = ( 660 x 209 ) / 12540

= 660 / 209

= 660

Step2:

LCM(11, 137) = 1507

GCD(11, 137) = ( 11 x 137 ) / 1507

= 11 / 137

= 11

Step3:

LCM(1, 723) = 723

GCD(1, 723) = ( 1 x 723 ) / 723

= 1 / 723

= 1

So, Greatest Common Divisor of 660, 209, 137, 723 is 1
