The common factors of 720 and 1809 are: 1, 3, and 9
The common factors of 90 and 720 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45 and 90.
The common factors of 504 and 720 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72.
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.
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.
