Given numbers are 649, 405, 249, 317
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 405) = 262845
GCD(649, 405) = ( 649 x 405 ) / 262845
= 649 / 405
= 649
Step2:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
Step3:
LCM(1, 317) = 317
GCD(1, 317) = ( 1 x 317 ) / 317
= 1 / 317
= 1
So, Greatest Common Divisor of 649, 405, 249, 317 is 1
