Given numbers are 633, 780, 247, 671

The list of prime factors of all numbers are

Prime factors of 633 are 3 x 211

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 247 are 13 x 19

Prime factors of 671 are 11 x 61

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

Given numbers are 633, 780, 247, 671

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

Apply this formula for all numbers.

Step1:

LCM(633, 780) = 164580

GCD(633, 780) = ( 633 x 780 ) / 164580

= 633 / 780

= 633

Step2:

LCM(3, 247) = 741

GCD(3, 247) = ( 3 x 247 ) / 741

= 3 / 247

= 3

Step3:

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

= 1 / 671

= 1

So, Greatest Common Divisor of 633, 780, 247, 671 is 1
