GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(580, 116) = 580
GCD(580, 116) = ( 580 x 116 ) / 580
= 580 / 116
= 580
Step2:
LCM(116, 345) = 40020
GCD(116, 345) = ( 116 x 345 ) / 40020
= 116 / 345
= 116
Step3:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
So, Greatest Common Divisor of 580, 116, 345, 399 is 1
