Steps to Calculate GCD of 310, 730, 79, 815 using LCM Formula
Given numbers are 310, 730, 79, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(310, 730) = 22630
GCD(310, 730) = ( 310 x 730 ) / 22630
= 310 / 730
= 310
Step2:
LCM(10, 79) = 790
GCD(10, 79) = ( 10 x 79 ) / 790
= 10 / 79
= 10
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 310, 730, 79, 815 is 1
