Steps to Calculate GCD of 72, 80, 66, 43 using LCM Formula

Given numbers are 72, 80, 66, 43

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

Apply this formula for all numbers.

Step1:

LCM(72, 80) = 720

GCD(72, 80) = ( 72 x 80 ) / 720

= 72 / 80

= 72


Step2:

LCM(8, 66) = 264

GCD(8, 66) = ( 8 x 66 ) / 264

= 8 / 66

= 8


Step3:

LCM(2, 43) = 86

GCD(2, 43) = ( 2 x 43 ) / 86

= 2 / 43

= 2


So, Greatest Common Divisor of 72, 80, 66, 43 is 1
