Given numbers are 688, 650, 390, 849

The list of prime factors of all numbers are

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

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 849 are 3 x 283

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

Given numbers are 688, 650, 390, 849

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

Apply this formula for all numbers.

Step1:

LCM(688, 650) = 223600

GCD(688, 650) = ( 688 x 650 ) / 223600

= 688 / 650

= 688

Step2:

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

= 2 / 390

= 2

Step3:

LCM(2, 849) = 1698

GCD(2, 849) = ( 2 x 849 ) / 1698

= 2 / 849

= 2

So, Greatest Common Divisor of 688, 650, 390, 849 is 1
