Steps to Calculate GCD of 69, 65, 71, 23 using LCM Formula
Given numbers are 69, 65, 71, 23
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(69, 65) = 4485
GCD(69, 65) = ( 69 x 65 ) / 4485
= 69 / 65
= 69
Step2:
LCM(1, 71) = 71
GCD(1, 71) = ( 1 x 71 ) / 71
= 1 / 71
= 1
Step3:
LCM(1, 23) = 23
GCD(1, 23) = ( 1 x 23 ) / 23
= 1 / 23
= 1
So, Greatest Common Divisor of 69, 65, 71, 23 is 1
