Given numbers are 986, 396, 580, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(986, 396) = 195228
GCD(986, 396) = ( 986 x 396 ) / 195228
= 986 / 396
= 986
Step2:
LCM(2, 580) = 580
GCD(2, 580) = ( 2 x 580 ) / 580
= 2 / 580
= 2
Step3:
LCM(2, 305) = 610
GCD(2, 305) = ( 2 x 305 ) / 610
= 2 / 305
= 2
So, Greatest Common Divisor of 986, 396, 580, 305 is 1
