Given numbers are 698, 685, 121, 672

The list of prime factors of all numbers are

Prime factors of 698 are 2 x 349

Prime factors of 685 are 5 x 137

Prime factors of 121 are 11 x 11

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 698, 685, 121, 672

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

Apply this formula for all numbers.

Step1:

LCM(698, 685) = 478130

GCD(698, 685) = ( 698 x 685 ) / 478130

= 698 / 685

= 698

Step2:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 698, 685, 121, 672 is 1
