Steps to Calculate GCD of 24, 36, 90, 42 using LCM Formula
Given numbers are 24, 36, 90, 42
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(24, 36) = 72
GCD(24, 36) = ( 24 x 36 ) / 72
= 24 / 36
= 24
Step2:
LCM(12, 90) = 180
GCD(12, 90) = ( 12 x 90 ) / 180
= 12 / 90
= 12
Step3:
LCM(6, 42) = 42
GCD(6, 42) = ( 6 x 42 ) / 42
= 6 / 42
= 6
So, Greatest Common Divisor of 24, 36, 90, 42 is 6
