Given numbers are 630, 565, 345, 161
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 565 are 5 x 113
Prime factors of 345 are 3 x 5 x 23
Prime factors of 161 are 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 630, 565, 345, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 565) = 71190
GCD(630, 565) = ( 630 x 565 ) / 71190
= 630 / 565
= 630
Step2:
LCM(5, 345) = 345
GCD(5, 345) = ( 5 x 345 ) / 345
= 5 / 345
= 5
Step3:
LCM(5, 161) = 805
GCD(5, 161) = ( 5 x 161 ) / 805
= 5 / 161
= 5
So, Greatest Common Divisor of 630, 565, 345, 161 is 1
