Finding GCD of 820, 546, 91 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(820, 546) = 223860
GCD(820, 546) = ( 820 x 546 ) / 223860
GCD(820, 546) = 447720 / 223860
GCD(820, 546) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 91
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 91) = 182
GCD(2, 91) = ( 2 x 91 ) / 182
GCD(2, 91) = 182 / 182
GCD(2, 91) = 1
GCD of 820, 546, 91 is 1
