The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 420, 622, 215, 863
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 622) = 130620
GCD(420, 622) = ( 420 x 622 ) / 130620
= 420 / 622
= 420
Step2:
LCM(2, 215) = 430
GCD(2, 215) = ( 2 x 215 ) / 430
= 2 / 215
= 2
Step3:
LCM(1, 863) = 863
GCD(1, 863) = ( 1 x 863 ) / 863
= 1 / 863
= 1
So, Greatest Common Divisor of 420, 622, 215, 863 is 1
