Steps to Calculate GCD of 146, 978, 822, 445 using LCM Formula
Given numbers are 146, 978, 822, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(146, 978) = 71394
GCD(146, 978) = ( 146 x 978 ) / 71394
= 146 / 978
= 146
Step2:
LCM(2, 822) = 822
GCD(2, 822) = ( 2 x 822 ) / 822
= 2 / 822
= 2
Step3:
LCM(2, 445) = 890
GCD(2, 445) = ( 2 x 445 ) / 890
= 2 / 445
= 2
So, Greatest Common Divisor of 146, 978, 822, 445 is 1
