Given numbers are 689, 630, 700, 938

The list of prime factors of all numbers are

Prime factors of 689 are 13 x 53

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 700 are 2 x 2 x 5 x 5 x 7

Prime factors of 938 are 2 x 7 x 67

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

Given numbers are 689, 630, 700, 938

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

Apply this formula for all numbers.

Step1:

LCM(689, 630) = 434070

GCD(689, 630) = ( 689 x 630 ) / 434070

= 689 / 630

= 689

Step2:

LCM(1, 700) = 700

GCD(1, 700) = ( 1 x 700 ) / 700

= 1 / 700

= 1

Step3:

LCM(1, 938) = 938

GCD(1, 938) = ( 1 x 938 ) / 938

= 1 / 938

= 1

So, Greatest Common Divisor of 689, 630, 700, 938 is 1
