Four: 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100.
Five: 60, 65, 70, 75, 80, 85, 90, 95, 100.
Eight: 56, 64, 72, 80, 88, 96.
Only 80 is on all three lists.
Oh, what a happy little question! To find how many 4-digit numbers are multiples of 9, we need to see how many multiples of 9 fall between 1000 and 9999. To do this, we divide the range's endpoints by 9 and subtract the whole numbers in between. By doing this gentle math, we can find the number of delightful 4-digit numbers that are multiples of 9.
There are 75 multiples of 12 between 100 and 1000.
4 and 8 are multiples of 2. 6 and 9 are multiples of 3. 40 and 50 are multiples of 10.
4, 8, 12, 16
4,8,12,16,20,24,28,32,36,40
44
They are: 64 and 80
it is 83
4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52.
All multiples of their lowest common multiple are multiple of all of them.lcm(2, 6, 8) = 2455 ÷ 24 = 2 r 7 → first multiple of 24 greater than 55 is 3 x 24 = 72101÷ 24 = 4 r 5 → last multiple of 24 less than 101 is 4 x 24 = 96→ the numbers 72 and 96 are multiples of 2, 6 & 8 between 55 and 101.
56
72
72 and 96
56 and 84 is.
80
60, 80 and 100
56 is one of four such numbers.
