GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 487) = 316063
GCD(649, 487) = ( 649 x 487 ) / 316063
= 649 / 487
= 649
Step2:
LCM(1, 589) = 589
GCD(1, 589) = ( 1 x 589 ) / 589
= 1 / 589
= 1
Step3:
LCM(1, 617) = 617
GCD(1, 617) = ( 1 x 617 ) / 617
= 1 / 617
= 1
So, Greatest Common Divisor of 649, 487, 589, 617 is 1
