To find two numbers that add up to 105, we can set up the equation x + y = 105, where x and y are the two numbers. There are many possible pairs of numbers that satisfy this equation, such as 50 and 55, 40 and 65, or even fractions like 52.5 and 52.5. The key is to recognize that the sum of any two numbers that differ by 105 will always equal 105.
The prime numbers (factors) of 105 are: 3,5,7
210
They can be: 210/2 = 105
Two pairs of numbers with 105 as their least common multiple are (15, 105) and (21, 105). This means that both pairs of numbers are multiples of 105 and their only common multiple is 105. The least common multiple is the smallest number that both numbers can divide evenly into.
100 + 5 110 - 5 21 x 5 525/5
There are more numbers that can go into 105 than just 2 numbers. 1,3,5,7,15,21,35,105 1=105 3=35 5=21 7=15
The Least Common Multiple (LCM) of two numbers is the smallest multiple that both numbers share. To find the LCM of 35 and 105, you first need to list the multiples of each number: 35 (35, 70, 105, 140, ...) and 105 (105, 210, 315, ...). The smallest multiple that both numbers share is 105. Therefore, the LCM of 35 and 105 is 105.
The prime factors of 105 are: 3,5,7
