The common factors of 720 and 1809 are: 1, 3, and 9
The common factors of 504 and 720 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72.
The common factors of 90 and 720 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45 and 90.
Oh, dude, the greatest common factor of 720? That's like the biggest number that can divide into 720 without leaving a remainder. So, let's see, the factors of 720 are 1, 2, 3, 4, 5, 6, 8, 9, 10, and so on. The greatest one that they all have in common is like the biggest, baddest factor they can all agree on. And that's 360!
The prime factors of 720 are 2, 2, 2, 2, 3, 3, and 5. The prime factors of 450 are 2, 3, 3, 5, and 5. The prime factors they have in common are 2, 3, 3, and 5, so the greatest common factor is 2 x 3 x 3 x 5 = 90.
To have a highest common factor you need to have more than 1 number other wise you carn't compare the sets of factors as there will only be 1 set of factors.
least common multiple of 504 and 720 is 5040.
720 is.
720 is.
The Least Common Multiple (LCM) for 72 80 is 720.
Least Common Multiple (LCM) for 480 720 is 1,440
This is a "least common multiple (LCM)" question in disguise. The prime factors of 16 are 2, 2, 2 and 2 The prime factors of 12 are 2, 2, and 3 The prime factors of 9 are 3 and 3 The prime factors of 10 are 2 and 5 So, the least common multiple (and any multiple) will have to have factors of * four 2s * two 3s * one 5 (2 x 2 x 2 x 2) x (3 x 3) x 5 = 16 x 9 x 5 = 720 To prove our findings * 720 ÷ 16 = 45 * 720 ÷ 12 = 60 * 720 ÷ 9 = 80 * 720 ÷ 10 = 72 These numbers will also evenly divide into any multiple of 720, such as 1,440, 2,160, 2,880 etc.
The Least Common Multiple (LCM) of (9,16,5) is 720
