GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 589) = 11780
GCD(620, 589) = ( 620 x 589 ) / 11780
= 620 / 589
= 620
Step2:
LCM(31, 315) = 9765
GCD(31, 315) = ( 31 x 315 ) / 9765
= 31 / 315
= 31
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 620, 589, 315, 981 is 1
