Steps to Calculate GCD of 90, 38, 64, 74 using LCM Formula
Given numbers are 90, 38, 64, 74
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(90, 38) = 1710
GCD(90, 38) = ( 90 x 38 ) / 1710
= 90 / 38
= 90
Step2:
LCM(2, 64) = 64
GCD(2, 64) = ( 2 x 64 ) / 64
= 2 / 64
= 2
Step3:
LCM(2, 74) = 74
GCD(2, 74) = ( 2 x 74 ) / 74
= 2 / 74
= 2
So, Greatest Common Divisor of 90, 38, 64, 74 is 2
