Given numbers are 663, 675, 747, 407

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 675 are 3 x 3 x 3 x 5 x 5

Prime factors of 747 are 3 x 3 x 83

Prime factors of 407 are 11 x 37

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

Given numbers are 663, 675, 747, 407

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

Apply this formula for all numbers.

Step1:

LCM(663, 675) = 149175

GCD(663, 675) = ( 663 x 675 ) / 149175

= 663 / 675

= 663

Step2:

LCM(3, 747) = 747

GCD(3, 747) = ( 3 x 747 ) / 747

= 3 / 747

= 3

Step3:

LCM(3, 407) = 1221

GCD(3, 407) = ( 3 x 407 ) / 1221

= 3 / 407

= 3

So, Greatest Common Divisor of 663, 675, 747, 407 is 1
