Given numbers are 815, 860, 404, 306
The list of prime factors of all numbers are
Prime factors of 815 are 5 x 163
Prime factors of 860 are 2 x 2 x 5 x 43
Prime factors of 404 are 2 x 2 x 101
Prime factors of 306 are 2 x 3 x 3 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 815, 860, 404, 306
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 860) = 140180
GCD(815, 860) = ( 815 x 860 ) / 140180
= 815 / 860
= 815
Step2:
LCM(5, 404) = 2020
GCD(5, 404) = ( 5 x 404 ) / 2020
= 5 / 404
= 5
Step3:
LCM(1, 306) = 306
GCD(1, 306) = ( 1 x 306 ) / 306
= 1 / 306
= 1
So, Greatest Common Divisor of 815, 860, 404, 306 is 1
