To find pairs of numbers with a least common multiple (LCM) of 40, we need to consider the prime factorization of 40, which is 2^3 * 5. Any pair of numbers whose prime factorization includes these factors can have a LCM of 40. For example, 8 and 10 have a LCM of 40 because 8 = 2^3 and 10 = 2 * 5. Another pair could be 20 and 40, as both have the prime factors of 40.
1, 2, 4, 5, 8, 10, 20, 40.
The sum of the first 40 odd numbers is 1,600.
These are the whole numbers that go into 400 evenly: 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400.
There are 40 odd numbers between 20 and 100. Remember that an odd number is every second number. There are 80 numbers between 20 and 100, so there are 40 odd numbers and 40 even numbers.
The prime numbers (factors) of 40 are: 2 and 5
The two whole numbers that go into 40 evenly are 1, 2, 4, 5, 8, 10, 20, and 40.
Called 'factors', the whole numbers that go into 40 evenly are: 1, 2, 4, 5, 8, 10, 20, 40.
The two prime factors of 40 are: 2 and 5
