Given numbers are 543, 400, 638, 686

The list of prime factors of all numbers are

Prime factors of 543 are 3 x 181

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 638 are 2 x 11 x 29

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

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

Given numbers are 543, 400, 638, 686

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

Apply this formula for all numbers.

Step1:

LCM(543, 400) = 217200

GCD(543, 400) = ( 543 x 400 ) / 217200

= 543 / 400

= 543

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 543, 400, 638, 686 is 1
