Given numbers are 121, 672, 742, 842

The list of prime factors of all numbers are

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

Prime factors of 742 are 2 x 7 x 53

Prime factors of 842 are 2 x 421

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

Given numbers are 121, 672, 742, 842

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

Apply this formula for all numbers.

Step1:

LCM(121, 672) = 81312

GCD(121, 672) = ( 121 x 672 ) / 81312

= 121 / 672

= 121

Step2:

LCM(1, 742) = 742

GCD(1, 742) = ( 1 x 742 ) / 742

= 1 / 742

= 1

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 121, 672, 742, 842 is 1
