Given numbers are 139, 242, 672, 770

The list of prime factors of all numbers are

Prime factors of 139 are 139

Prime factors of 242 are 2 x 11 x 11

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

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 139, 242, 672, 770

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

Apply this formula for all numbers.

Step1:

LCM(139, 242) = 33638

GCD(139, 242) = ( 139 x 242 ) / 33638

= 139 / 242

= 139

Step2:

LCM(1, 672) = 672

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

= 1 / 672

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 139, 242, 672, 770 is 1
