GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(818, 643) = 525974
GCD(818, 643) = ( 818 x 643 ) / 525974
= 818 / 643
= 818
Step2:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
Step3:
LCM(1, 319) = 319
GCD(1, 319) = ( 1 x 319 ) / 319
= 1 / 319
= 1
So, Greatest Common Divisor of 818, 643, 790, 319 is 1
