Steps to Calculate GCD of 515, 485, 578, 121 using LCM Formula
Given numbers are 515, 485, 578, 121
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 485) = 49955
GCD(515, 485) = ( 515 x 485 ) / 49955
= 515 / 485
= 515
Step2:
LCM(5, 578) = 2890
GCD(5, 578) = ( 5 x 578 ) / 2890
= 5 / 578
= 5
Step3:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
So, Greatest Common Divisor of 515, 485, 578, 121 is 1
