Given numbers are 686, 840, 447, 213

The list of prime factors of all numbers are

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 447 are 3 x 149

Prime factors of 213 are 3 x 71

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

Given numbers are 686, 840, 447, 213

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

Apply this formula for all numbers.

Step1:

LCM(686, 840) = 41160

GCD(686, 840) = ( 686 x 840 ) / 41160

= 686 / 840

= 686

Step2:

LCM(14, 447) = 6258

GCD(14, 447) = ( 14 x 447 ) / 6258

= 14 / 447

= 14

Step3:

LCM(1, 213) = 213

GCD(1, 213) = ( 1 x 213 ) / 213

= 1 / 213

= 1

So, Greatest Common Divisor of 686, 840, 447, 213 is 1
