Given numbers are 398, 210, 189, 939
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 210) = 41790
GCD(398, 210) = ( 398 x 210 ) / 41790
= 398 / 210
= 398
Step2:
LCM(2, 189) = 378
GCD(2, 189) = ( 2 x 189 ) / 378
= 2 / 189
= 2
Step3:
LCM(1, 939) = 939
GCD(1, 939) = ( 1 x 939 ) / 939
= 1 / 939
= 1
So, Greatest Common Divisor of 398, 210, 189, 939 is 1
