Given numbers are 694, 316, 819, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(694, 316) = 109652
GCD(694, 316) = ( 694 x 316 ) / 109652
= 694 / 316
= 694
Step2:
LCM(2, 819) = 1638
GCD(2, 819) = ( 2 x 819 ) / 1638
= 2 / 819
= 2
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 694, 316, 819, 420 is 1
