Steps to Calculate GCD of 555, 409, 65, 165 using LCM Formula
Given numbers are 555, 409, 65, 165
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(555, 409) = 226995
GCD(555, 409) = ( 555 x 409 ) / 226995
= 555 / 409
= 555
Step2:
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
= 1 / 65
= 1
Step3:
LCM(1, 165) = 165
GCD(1, 165) = ( 1 x 165 ) / 165
= 1 / 165
= 1
So, Greatest Common Divisor of 555, 409, 65, 165 is 1
