Given numbers are 424, 820, 421, 344
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(424, 820) = 86920
GCD(424, 820) = ( 424 x 820 ) / 86920
= 424 / 820
= 424
Step2:
LCM(4, 421) = 1684
GCD(4, 421) = ( 4 x 421 ) / 1684
= 4 / 421
= 4
Step3:
LCM(1, 344) = 344
GCD(1, 344) = ( 1 x 344 ) / 344
= 1 / 344
= 1
So, Greatest Common Divisor of 424, 820, 421, 344 is 1
