Steps to Calculate GCD of 490, 203, 319, 123 using LCM Formula
Given numbers are 490, 203, 319, 123
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 203) = 14210
GCD(490, 203) = ( 490 x 203 ) / 14210
= 490 / 203
= 490
Step2:
LCM(7, 319) = 2233
GCD(7, 319) = ( 7 x 319 ) / 2233
= 7 / 319
= 7
Step3:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
So, Greatest Common Divisor of 490, 203, 319, 123 is 1
