Given numbers are 453, 140, 340, 687

The list of prime factors of all numbers are

Prime factors of 453 are 3 x 151

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

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 687 are 3 x 229

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

Given numbers are 453, 140, 340, 687

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

Apply this formula for all numbers.

Step1:

LCM(453, 140) = 63420

GCD(453, 140) = ( 453 x 140 ) / 63420

= 453 / 140

= 453

Step2:

LCM(1, 340) = 340

GCD(1, 340) = ( 1 x 340 ) / 340

= 1 / 340

= 1

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 453, 140, 340, 687 is 1
