Given numbers are 651, 203, 686, 213

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 203 are 7 x 29

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

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 651, 203, 686, 213

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

Apply this formula for all numbers.

Step1:

LCM(651, 203) = 18879

GCD(651, 203) = ( 651 x 203 ) / 18879

= 651 / 203

= 651

Step2:

LCM(7, 686) = 686

GCD(7, 686) = ( 7 x 686 ) / 686

= 7 / 686

= 7

Step3:

LCM(7, 213) = 1491

GCD(7, 213) = ( 7 x 213 ) / 1491

= 7 / 213

= 7

So, Greatest Common Divisor of 651, 203, 686, 213 is 1
