Given numbers are 694, 406, 438, 811
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(694, 406) = 140882
GCD(694, 406) = ( 694 x 406 ) / 140882
= 694 / 406
= 694
Step2:
LCM(2, 438) = 438
GCD(2, 438) = ( 2 x 438 ) / 438
= 2 / 438
= 2
Step3:
LCM(2, 811) = 1622
GCD(2, 811) = ( 2 x 811 ) / 1622
= 2 / 811
= 2
So, Greatest Common Divisor of 694, 406, 438, 811 is 1
