GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(694, 346) = 120062
GCD(694, 346) = ( 694 x 346 ) / 120062
= 694 / 346
= 694
Step2:
LCM(2, 258) = 258
GCD(2, 258) = ( 2 x 258 ) / 258
= 2 / 258
= 2
Step3:
LCM(2, 210) = 210
GCD(2, 210) = ( 2 x 210 ) / 210
= 2 / 210
= 2
So, Greatest Common Divisor of 694, 346, 258, 210 is 2
