Given numbers are 449, 721, 617, 705
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(449, 721) = 323729
GCD(449, 721) = ( 449 x 721 ) / 323729
= 449 / 721
= 449
Step2:
LCM(1, 617) = 617
GCD(1, 617) = ( 1 x 617 ) / 617
= 1 / 617
= 1
Step3:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
So, Greatest Common Divisor of 449, 721, 617, 705 is 1
