Given numbers are 441, 460, 390, 449
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(441, 460) = 202860
GCD(441, 460) = ( 441 x 460 ) / 202860
= 441 / 460
= 441
Step2:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
Step3:
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
= 1 / 449
= 1
So, Greatest Common Divisor of 441, 460, 390, 449 is 1
