Steps to Calculate GCD of 42, 34, 19, 54 using LCM Formula
Given numbers are 42, 34, 19, 54
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(42, 34) = 714
GCD(42, 34) = ( 42 x 34 ) / 714
= 42 / 34
= 42
Step2:
LCM(2, 19) = 38
GCD(2, 19) = ( 2 x 19 ) / 38
= 2 / 19
= 2
Step3:
LCM(1, 54) = 54
GCD(1, 54) = ( 1 x 54 ) / 54
= 1 / 54
= 1
So, Greatest Common Divisor of 42, 34, 19, 54 is 1
