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 531 are 3 x 3 x 59
Prime factors of 808 are 2 x 2 x 2 x 101
Prime factors of 147 are 3 x 7 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 630, 531, 808, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 531) = 37170
GCD(630, 531) = ( 630 x 531 ) / 37170
= 630 / 531
= 630
Step2:
LCM(9, 808) = 7272
GCD(9, 808) = ( 9 x 808 ) / 7272
= 9 / 808
= 9
Step3:
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
= 1 / 147
= 1
So, Greatest Common Divisor of 630, 531, 808, 147 is 1
