GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 591) = 128247
GCD(217, 591) = ( 217 x 591 ) / 128247
= 217 / 591
= 217
Step2:
LCM(1, 783) = 783
GCD(1, 783) = ( 1 x 783 ) / 783
= 1 / 783
= 1
Step3:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
So, Greatest Common Divisor of 217, 591, 783, 399 is 1
