Given numbers are 843, 415, 221, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(843, 415) = 349845
GCD(843, 415) = ( 843 x 415 ) / 349845
= 843 / 415
= 843
Step2:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 843, 415, 221, 643 is 1
