how many numbers less than or equal to 800 are multiples of both 2 and 5
To find the number of multiples of both 2 and 5, we need to find the least common multiple (LCM) of 2 and 5.
The LCM of 2 and 5 is simply their product, which is 2 x 5 = 10.
Now, we need to count how many multiples of 10 are less than or equal to 800.
Dividing 800 by 10 gives us 80, so there are 80 multiples of 10 that are less than or equal to 800.
Therefore, there are 80 numbers less than or equal to 800 that are multiples of both 2 and 5.
To find the number of numbers less than or equal to 800 that are multiples of both 2 and 5, we need to find the least common multiple (LCM) of 2 and 5 first. The LCM of 2 and 5 is 10.
To find how many numbers less than or equal to 800 are multiples of 10, we divide 800 by 10:
800 รท 10 = 80
Therefore, there are 80 numbers less than or equal to 800 that are multiples of both 2 and 5.
To find the number of numbers that are multiples of both 2 and 5 and less than or equal to 800, we can use the concept of "Least Common Multiple" (LCM).
The LCM of two numbers is the smallest number that is divisible by both numbers. In this case, the LCM of 2 and 5 is 10.
To find the count of numbers less than or equal to 800 that are multiples of 10, we can divide 800 by 10 and round down to the nearest whole number.
So, the calculation would be: 800 / 10 = 80.
Therefore, there are 80 numbers less than or equal to 800 that are multiples of both 2 and 5.
