Finding GCD of 805, 756, 215 using LCM Formula
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(805, 756) = 86940
GCD(805, 756) = ( 805 x 756 ) / 86940
GCD(805, 756) = 608580 / 86940
GCD(805, 756) = 7
Step2:
Here we consider the GCD from the above i.e. 7 as first number and the next as 215
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 215) = 1505
GCD(7, 215) = ( 7 x 215 ) / 1505
GCD(7, 215) = 1505 / 1505
GCD(7, 215) = 1
GCD of 805, 756, 215 is 1
