Steps to Calculate GCD of 55, 80, 70, 54 using LCM Formula
Given numbers are 55, 80, 70, 54
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(55, 80) = 880
GCD(55, 80) = ( 55 x 80 ) / 880
= 55 / 80
= 55
Step2:
LCM(5, 70) = 70
GCD(5, 70) = ( 5 x 70 ) / 70
= 5 / 70
= 5
Step3:
LCM(5, 54) = 270
GCD(5, 54) = ( 5 x 54 ) / 270
= 5 / 54
= 5
So, Greatest Common Divisor of 55, 80, 70, 54 is 1
