All composite numbers have more than 2 factors but prime numbers have only 2 factors
To find common factors, you first need to break the numbers up into their prime factors: 9=3x3 100=2x2x5x5 The next step would be to identify the common prime factors. In this case we can see that there are none, and thus the HCF, and indeed the only number that goes into both 9 and 100, is 1.
64 and 96 have the longest prime factorizations in that range. If you're asking about distinct prime factors, quite a few are tied with three.
by finding the prime numbers up to 100
No, there are only 25 prime numbers less than 100.........remember that 1 is classed as unity and is not a prime number and 2 is the only even prime number.
A multiplication sentence where prime factors total a given composite number is known as a prime factorization.
the prime factors of 72 are 2 and 3 6,12, and 1 (also factors) sum up to 19
A number is relatively prime to a number if it has no common prime factors with that number. To calculate relative primes, we need to break 170 down into its prime factors. These are: 2, 5, 17. Thus we want to find a number that is made up solely from multiplying 3s, 7s, 11s, 13s, 19s, 23s, 29s and 31s together. The largest number less than 100 that meets this criteria is 99, which has prime factors of 3, 3 and 11.
To find the LCM of 100 and 125, you first need to break them up into their prime factors: 100 = 2x2x5x5 125 = 5x5x5 The next step is to identify any common factors. In this case, both numbers have two 5s as prime factors. Thus we can discard two of these. That leaves us with 2, 2, 5, 5 and 5. Multiply these together to find the LCM: 2x2x5x5x5 = 500 Thus the LCM of 100 and 125 is 500.
There are no two prime numbers in which a product of 100 is possible.
There are 25 prime numbers up to 100.
Prime numbers are infinite.
