Yes, yes, and yes.
No, but it is a common multiple.
240
the common multiple of 9 15 30 is 90
The least common multiple of the numbers 30, 15 and 9 is 90.
Yes, 80x9=720
The answer is 540
The Least Common Multiple (LCM) of (9,16,5) is 720
The Least Common Multiple (LCM) for 9 6 15 is 90.
The common factors of 90 and 720 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45 and 90.
1 × 720 = 720 2 × 360 = 720 3 × 240 = 720 4 × 180 = 720 5 × 144 = 720 6 × 120 = 720 8 × 90 = 720 9 × 80 = 720 10 × 72 = 720 12 × 60 = 720 15 × 48 = 720 16 × 45 = 720 18 × 40 = 720 20 × 36 = 720 24 × 30 = 720
The LCM of these numbers is 720. LCM is Least Common Multiple.
The lowest common multiple of 9, 6 and 30 is 90. 9 x 10 = 90, 6 x 15 = 90 and 30 x 3 = 90.
