Given numbers are 672, 686, 541, 640

The list of prime factors of all numbers are

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Prime factors of 541 are 541

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 672, 686, 541, 640

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

Apply this formula for all numbers.

Step1:

LCM(672, 686) = 32928

GCD(672, 686) = ( 672 x 686 ) / 32928

= 672 / 686

= 672

Step2:

LCM(14, 541) = 7574

GCD(14, 541) = ( 14 x 541 ) / 7574

= 14 / 541

= 14

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 672, 686, 541, 640 is 1
