Given numbers are 630, 240, 449, 185
The list of prime factors of all numbers are
Prime factors of 630 are 2 x 3 x 3 x 5 x 7
Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5
Prime factors of 449 are 449
Prime factors of 185 are 5 x 37
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 630, 240, 449, 185
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 240) = 5040
GCD(630, 240) = ( 630 x 240 ) / 5040
= 630 / 240
= 630
Step2:
LCM(30, 449) = 13470
GCD(30, 449) = ( 30 x 449 ) / 13470
= 30 / 449
= 30
Step3:
LCM(1, 185) = 185
GCD(1, 185) = ( 1 x 185 ) / 185
= 1 / 185
= 1
So, Greatest Common Divisor of 630, 240, 449, 185 is 1
