GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(845, 605) = 102245
GCD(845, 605) = ( 845 x 605 ) / 102245
= 845 / 605
= 845
Step2:
LCM(5, 818) = 4090
GCD(5, 818) = ( 5 x 818 ) / 4090
= 5 / 818
= 5
Step3:
LCM(1, 315) = 315
GCD(1, 315) = ( 1 x 315 ) / 315
= 1 / 315
= 1
So, Greatest Common Divisor of 845, 605, 818, 315 is 1
