Given numbers are 807, 990, 653, 663

The list of prime factors of all numbers are

Prime factors of 807 are 3 x 269

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 653 are 653

Prime factors of 663 are 3 x 13 x 17

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

Given numbers are 807, 990, 653, 663

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

Apply this formula for all numbers.

Step1:

LCM(807, 990) = 266310

GCD(807, 990) = ( 807 x 990 ) / 266310

= 807 / 990

= 807

Step2:

LCM(3, 653) = 1959

GCD(3, 653) = ( 3 x 653 ) / 1959

= 3 / 653

= 3

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 807, 990, 653, 663 is 1
