Given numbers are 622, 420, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(622, 420) = 130620
GCD(622, 420) = ( 622 x 420 ) / 130620
= 622 / 420
= 622
Step2:
LCM(2, 247) = 494
GCD(2, 247) = ( 2 x 247 ) / 494
= 2 / 247
= 2
So, Greatest Common Divisor of 622, 420, 247 is 1
