Steps to Calculate GCD of 32, 81, 70, 23 using LCM Formula
Given numbers are 32, 81, 70, 23
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(32, 81) = 2592
GCD(32, 81) = ( 32 x 81 ) / 2592
= 32 / 81
= 32
Step2:
LCM(1, 70) = 70
GCD(1, 70) = ( 1 x 70 ) / 70
= 1 / 70
= 1
Step3:
LCM(1, 23) = 23
GCD(1, 23) = ( 1 x 23 ) / 23
= 1 / 23
= 1
So, Greatest Common Divisor of 32, 81, 70, 23 is 1
