Steps to Calculate GCD of 45, 58, 66, 80 using LCM Formula
Given numbers are 45, 58, 66, 80
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(45, 58) = 2610
GCD(45, 58) = ( 45 x 58 ) / 2610
= 45 / 58
= 45
Step2:
LCM(1, 66) = 66
GCD(1, 66) = ( 1 x 66 ) / 66
= 1 / 66
= 1
Step3:
LCM(1, 80) = 80
GCD(1, 80) = ( 1 x 80 ) / 80
= 1 / 80
= 1
So, Greatest Common Divisor of 45, 58, 66, 80 is 1
