GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(806, 620) = 8060
GCD(806, 620) = ( 806 x 620 ) / 8060
= 806 / 620
= 806
Step2:
LCM(62, 385) = 23870
GCD(62, 385) = ( 62 x 385 ) / 23870
= 62 / 385
= 62
So, Greatest Common Divisor of 806, 620, 385 is 1
