Steps to Calculate GCD of 23, 68, 45, 45 using LCM Formula

Given numbers are 23, 68, 45, 45

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(23, 68) = 1564

GCD(23, 68) = ( 23 x 68 ) / 1564

= 23 / 68

= 23


Step2:

LCM(1, 45) = 45

GCD(1, 45) = ( 1 x 45 ) / 45

= 1 / 45

= 1


Step3:

LCM(1, 45) = 45

GCD(1, 45) = ( 1 x 45 ) / 45

= 1 / 45

= 1


So, Greatest Common Divisor of 23, 68, 45, 45 is 1
