GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(856, 491) = 420296
GCD(856, 491) = ( 856 x 491 ) / 420296
= 856 / 491
= 856
Step2:
LCM(1, 332) = 332
GCD(1, 332) = ( 1 x 332 ) / 332
= 1 / 332
= 1
Step3:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
So, Greatest Common Divisor of 856, 491, 332, 210 is 1
