GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(919, 643) = 590917
GCD(919, 643) = ( 919 x 643 ) / 590917
= 919 / 643
= 919
Step2:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
Step3:
LCM(1, 259) = 259
GCD(1, 259) = ( 1 x 259 ) / 259
= 1 / 259
= 1
So, Greatest Common Divisor of 919, 643, 221, 259 is 1
