Given numbers are 649, 681, 864, 449
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 681) = 441969
GCD(649, 681) = ( 649 x 681 ) / 441969
= 649 / 681
= 649
Step2:
LCM(1, 864) = 864
GCD(1, 864) = ( 1 x 864 ) / 864
= 1 / 864
= 1
Step3:
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
= 1 / 449
= 1
So, Greatest Common Divisor of 649, 681, 864, 449 is 1
