GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(694, 980) = 340060
GCD(694, 980) = ( 694 x 980 ) / 340060
= 694 / 980
= 694
Step2:
LCM(2, 398) = 398
GCD(2, 398) = ( 2 x 398 ) / 398
= 2 / 398
= 2
Step3:
LCM(2, 930) = 930
GCD(2, 930) = ( 2 x 930 ) / 930
= 2 / 930
= 2
So, Greatest Common Divisor of 694, 980, 398, 930 is 2
