Well I need the LCM for 78& 104 ok there
When finding LCM, there are several way to figure it out but the one I use it finding prime factors.
78 104
39x2 52x2
(13x3x2) (13x4x2)
You eliminate 1 of the double so now it is; 13x3x2x4= 312
get it?
The least common multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.
What number will 78 and 104 both go into evenly?
Start by multiplying 78 by 2, then 3, then 4, etc., until find one that is divisible by 104. Hint: it's less than 6 times 78.
oh thanks gina are you a student
not it multiples like 2 4 6 8 10...
To find the Least Common Multiple (LCM) of two numbers, such as 78 and 104, you can follow these steps:
Step 1: Prime factorize both numbers.
To prime factorize a number, you break it down into its prime factors, which are the prime numbers that multiply together to give the original number.
78 can be prime factorized as:
78 = 2 * 3 * 13
104 can be prime factorized as:
104 = 2 * 2 * 2 * 13
Step 2: Identify the highest power of each prime factor.
Look at the prime factorization of both numbers and find the highest power of each prime factor. Take each prime factor and use the highest exponent that appears.
In this case, the prime factors are 2, 3, and 13. The highest powers are:
2^3, 3^1, and 13^1.
Step 3: Multiply the highest powers of the prime factors.
Multiply the highest powers obtained in the previous step:
2^3 * 3^1 * 13^1 = 8 * 3 * 13 = 312
Therefore, the LCM of 78 and 104 is 312.
