Finding GCD of 660, 647, 761 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(660, 647) = 427020
GCD(660, 647) = ( 660 x 647 ) / 427020
GCD(660, 647) = 427020 / 427020
GCD(660, 647) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 761
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 761) = 761
GCD(1, 761) = ( 1 x 761 ) / 761
GCD(1, 761) = 761 / 761
GCD(1, 761) = 1
GCD of 660, 647, 761 is 1
