GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(494, 210) = 51870
GCD(494, 210) = ( 494 x 210 ) / 51870
= 494 / 210
= 494
Step2:
LCM(2, 490) = 490
GCD(2, 490) = ( 2 x 490 ) / 490
= 2 / 490
= 2
Step3:
LCM(2, 858) = 858
GCD(2, 858) = ( 2 x 858 ) / 858
= 2 / 858
= 2
So, Greatest Common Divisor of 494, 210, 490, 858 is 2
