Steps to Calculate GCD of 20, 49, 62, 54 using LCM Formula
Given numbers are 20, 49, 62, 54
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(20, 49) = 980
GCD(20, 49) = ( 20 x 49 ) / 980
= 20 / 49
= 20
Step2:
LCM(1, 62) = 62
GCD(1, 62) = ( 1 x 62 ) / 62
= 1 / 62
= 1
Step3:
LCM(1, 54) = 54
GCD(1, 54) = ( 1 x 54 ) / 54
= 1 / 54
= 1
So, Greatest Common Divisor of 20, 49, 62, 54 is 1
