Given numbers are 643, 338, 673, 493
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 338) = 217334
GCD(643, 338) = ( 643 x 338 ) / 217334
= 643 / 338
= 643
Step2:
LCM(1, 673) = 673
GCD(1, 673) = ( 1 x 673 ) / 673
= 1 / 673
= 1
Step3:
LCM(1, 493) = 493
GCD(1, 493) = ( 1 x 493 ) / 493
= 1 / 493
= 1
So, Greatest Common Divisor of 643, 338, 673, 493 is 1
