The list of prime factors of all numbers are
Prime factors of 171 are 3 x 3 x 19
Prime factors of 630 are 2 x 3 x 3 x 5 x 7
Prime factors of 247 are 13 x 19
Prime factors of 451 are 11 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 171, 630, 247, 451
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(171, 630) = 11970
GCD(171, 630) = ( 171 x 630 ) / 11970
= 171 / 630
= 171
Step2:
LCM(9, 247) = 2223
GCD(9, 247) = ( 9 x 247 ) / 2223
= 9 / 247
= 9
Step3:
LCM(1, 451) = 451
GCD(1, 451) = ( 1 x 451 ) / 451
= 1 / 451
= 1
So, Greatest Common Divisor of 171, 630, 247, 451 is 1
