Steps to Calculate GCD of 91, 24, 65, 69 using LCM Formula
Given numbers are 91, 24, 65, 69
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(91, 24) = 2184
GCD(91, 24) = ( 91 x 24 ) / 2184
= 91 / 24
= 91
Step2:
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
= 1 / 65
= 1
Step3:
LCM(1, 69) = 69
GCD(1, 69) = ( 1 x 69 ) / 69
= 1 / 69
= 1
So, Greatest Common Divisor of 91, 24, 65, 69 is 1
