Given numbers are 682, 252, 391, 105

The list of prime factors of all numbers are

Prime factors of 682 are 2 x 11 x 31

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 391 are 17 x 23

Prime factors of 105 are 3 x 5 x 7

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

Given numbers are 682, 252, 391, 105

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

Apply this formula for all numbers.

Step1:

LCM(682, 252) = 85932

GCD(682, 252) = ( 682 x 252 ) / 85932

= 682 / 252

= 682

Step2:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

Step3:

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

= 1 / 105

= 1

So, Greatest Common Divisor of 682, 252, 391, 105 is 1
