Finding GCD of 978, 840, 355 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(978, 840) = 136920
GCD(978, 840) = ( 978 x 840 ) / 136920
GCD(978, 840) = 821520 / 136920
GCD(978, 840) = 6
Step2:
Here we consider the GCD from the above i.e. 6 as first number and the next as 355
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 355) = 2130
GCD(6, 355) = ( 6 x 355 ) / 2130
GCD(6, 355) = 2130 / 2130
GCD(6, 355) = 1
GCD of 978, 840, 355 is 1
