Given numbers are 231, 620, 774, 140

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 774 are 2 x 3 x 3 x 43

Prime factors of 140 are 2 x 2 x 5 x 7

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

Given numbers are 231, 620, 774, 140

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

Apply this formula for all numbers.

Step1:

LCM(231, 620) = 143220

GCD(231, 620) = ( 231 x 620 ) / 143220

= 231 / 620

= 231

Step2:

LCM(1, 774) = 774

GCD(1, 774) = ( 1 x 774 ) / 774

= 1 / 774

= 1

Step3:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

So, Greatest Common Divisor of 231, 620, 774, 140 is 1
