504 is the least common multiple of 7, 8 and 9. All numbers that are multiples of 504 are multiples of 7, 8 and 9 as well
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
Multiples of 360.
Just 72. It was found by multiplying 8 and 9. --------------------------------------- The common multiples of two numbers are the multiples of their lowest common multiple. LCM(8, 9) = 72 The common multiples of 8 and 9 are 72, 144, 216, ... The only common multiples less than 100 are 72 only.
504, 1008, 1512 and so on.
72, 144, 216
There is an infinite number of common multiples for 9 and 8. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
All numbers that are multiples of 360 are multiples of 6, 8 and 10.
Multiples of 8
There are 720 of them. The three digit counting numbers are 100-999. All multiples of 5 have their last digit as 0 or 5. There are 9 possible numbers {1-9} for the first digit, There are 10 possible numbers {0-9} for each of the first digits, There are 8 possible numbers {1-4, 6-9} for each of the first two digits, Making 9 x 10 x 8 = 720 possible 3 digit counting numbers not multiples of 5.
There is an infinite number of common multiples for 2 8 and 9. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 2 8 and 9 is 72.
33 multiples of 3 plus 12 multiples of 8 minus 4 multiples of both. 41%
