Given numbers are 620, 805, 908, 361
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 805) = 99820
GCD(620, 805) = ( 620 x 805 ) / 99820
= 620 / 805
= 620
Step2:
LCM(5, 908) = 4540
GCD(5, 908) = ( 5 x 908 ) / 4540
= 5 / 908
= 5
Step3:
LCM(1, 361) = 361
GCD(1, 361) = ( 1 x 361 ) / 361
= 1 / 361
= 1
So, Greatest Common Divisor of 620, 805, 908, 361 is 1
