Given numbers are 409, 682, 620, 361
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 682) = 278938
GCD(409, 682) = ( 409 x 682 ) / 278938
= 409 / 682
= 409
Step2:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
Step3:
LCM(1, 361) = 361
GCD(1, 361) = ( 1 x 361 ) / 361
= 1 / 361
= 1
So, Greatest Common Divisor of 409, 682, 620, 361 is 1
