GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 858) = 184470
GCD(215, 858) = ( 215 x 858 ) / 184470
= 215 / 858
= 215
Step2:
LCM(1, 580) = 580
GCD(1, 580) = ( 1 x 580 ) / 580
= 1 / 580
= 1
Step3:
LCM(1, 918) = 918
GCD(1, 918) = ( 1 x 918 ) / 918
= 1 / 918
= 1
So, Greatest Common Divisor of 215, 858, 580, 918 is 1
