The list of prime factors of all numbers are
Prime factors of 115 are 5 x 23
Prime factors of 655 are 5 x 131
Prime factors of 306 are 2 x 3 x 3 x 17
Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 115, 655, 306, 624
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 655) = 15065
GCD(115, 655) = ( 115 x 655 ) / 15065
= 115 / 655
= 115
Step2:
LCM(5, 306) = 1530
GCD(5, 306) = ( 5 x 306 ) / 1530
= 5 / 306
= 5
Step3:
LCM(1, 624) = 624
GCD(1, 624) = ( 1 x 624 ) / 624
= 1 / 624
= 1
So, Greatest Common Divisor of 115, 655, 306, 624 is 1
