Given numbers are 630, 157, 645, 475
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 157 are 157
Prime factors of 645 are 3 x 5 x 43
Prime factors of 475 are 5 x 5 x 19
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 630, 157, 645, 475
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 157) = 98910
GCD(630, 157) = ( 630 x 157 ) / 98910
= 630 / 157
= 630
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 475) = 475
GCD(1, 475) = ( 1 x 475 ) / 475
= 1 / 475
= 1
So, Greatest Common Divisor of 630, 157, 645, 475 is 1
