Finding GCD of 121, 891, 985 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(121, 891) = 9801
GCD(121, 891) = ( 121 x 891 ) / 9801
GCD(121, 891) = 107811 / 9801
GCD(121, 891) = 11
Step2:
Here we consider the GCD from the above i.e. 11 as first number and the next as 985
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(11, 985) = 10835
GCD(11, 985) = ( 11 x 985 ) / 10835
GCD(11, 985) = 10835 / 10835
GCD(11, 985) = 1
GCD of 121, 891, 985 is 1
