Steps to Calculate GCD of 11, 69, 45, 64 using LCM Formula
Given numbers are 11, 69, 45, 64
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(11, 69) = 759
GCD(11, 69) = ( 11 x 69 ) / 759
= 11 / 69
= 11
Step2:
LCM(1, 45) = 45
GCD(1, 45) = ( 1 x 45 ) / 45
= 1 / 45
= 1
Step3:
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
= 1 / 64
= 1
So, Greatest Common Divisor of 11, 69, 45, 64 is 1
