Given numbers are 630, 345, 661, 493
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 345 are 3 x 5 x 23
Prime factors of 661 are 661
Prime factors of 493 are 17 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 630, 345, 661, 493
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 345) = 14490
GCD(630, 345) = ( 630 x 345 ) / 14490
= 630 / 345
= 630
Step2:
LCM(15, 661) = 9915
GCD(15, 661) = ( 15 x 661 ) / 9915
= 15 / 661
= 15
Step3:
LCM(1, 493) = 493
GCD(1, 493) = ( 1 x 493 ) / 493
= 1 / 493
= 1
So, Greatest Common Divisor of 630, 345, 661, 493 is 1
