Prime factorization: It is a method to express each number as the product of prime numbers.Step 1: Which prime number divide 75?Ans: 3 and 5.But, we should start with the smallest prime number which divides 75.75÷3 = 25Step 2: Which prime number divide 25?Ans: 525÷5 = 5Step 3: We have to continuously divide each quotient by a prime number until the quotient itself is a prime number.In step 2 we are left with 5(prime number) as a quotient.So, prime factorization of 75 = product of all the quotients = 3x5x5
Method to find LCM of two numbers a & b:1- Find GCF of a & b.2- Find product of a & b.3- Divide the result obtained in step 2 by the GCF. The result is LCM of a & b.1- GCF of 36 & 80 = ?Prime factorization of 36 = 2x2x3x3Prime factorization of 80 = 2x2x2x2x2x5GCF = 42- Product of 36 & 80 = 28803- LCM = 2880/4 = 720
yes its 3x5x5

The prime factorization of 93 is 3 x 31. Draw it however you wish.
290 145,2 29,5,2 2 x 5 x 29 = 290
It is: 2*2*5*5 = 100
It is itself because 31 is a prime number
You can find the prime factorization of 130: 130 = 2*5*13 Therefore the answer is 1. Or you can skip a step. Just divide 130 by 2. You get 65, which is an odd number. Therefore there is only 1 factor of 2 in the factorization of 130.
To find the Least Common Multiple (LCM) of 6, 7, and 18, we first need to find the prime factorization of each number. The prime factorization of 6 is 2 x 3, the prime factorization of 7 is 7, and the prime factorization of 18 is 2 x 3^2. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers, which gives us 2 x 3^2 x 7 = 126. Therefore, the LCM of 6, 7, and 18 is 126.
Notice whether the number is odd or even. If it's even, the first prime factor is 2.
