Given numbers are 648, 237, 689, 102

The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 237 are 3 x 79

Prime factors of 689 are 13 x 53

Prime factors of 102 are 2 x 3 x 17

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

Given numbers are 648, 237, 689, 102

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

Apply this formula for all numbers.

Step1:

LCM(648, 237) = 51192

GCD(648, 237) = ( 648 x 237 ) / 51192

= 648 / 237

= 648

Step2:

LCM(3, 689) = 2067

GCD(3, 689) = ( 3 x 689 ) / 2067

= 3 / 689

= 3

Step3:

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

= 1 / 102

= 1

So, Greatest Common Divisor of 648, 237, 689, 102 is 1
