Given numbers are 813, 330, 647, 449
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 330) = 89430
GCD(813, 330) = ( 813 x 330 ) / 89430
= 813 / 330
= 813
Step2:
LCM(3, 647) = 1941
GCD(3, 647) = ( 3 x 647 ) / 1941
= 3 / 647
= 3
Step3:
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
= 1 / 449
= 1
So, Greatest Common Divisor of 813, 330, 647, 449 is 1
