Steps to Calculate GCD of 478, 290, 649, 214 using LCM Formula
Given numbers are 478, 290, 649, 214
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 290) = 69310
GCD(478, 290) = ( 478 x 290 ) / 69310
= 478 / 290
= 478
Step2:
LCM(2, 649) = 1298
GCD(2, 649) = ( 2 x 649 ) / 1298
= 2 / 649
= 2
Step3:
LCM(1, 214) = 214
GCD(1, 214) = ( 1 x 214 ) / 214
= 1 / 214
= 1
So, Greatest Common Divisor of 478, 290, 649, 214 is 1
