The greatest common factor (GCF) of 15, 25, and 40 is 5. To find the GCF, you need to determine the factors of each number and identify the largest factor that is common to all three numbers. The factors of 15 are 1, 3, 5, and 15. The factors of 25 are 1, 5, and 25. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The largest factor that is common to all three numbers is 5, making it the greatest common factor.
Oh, what a happy little question! Let's see here... We have 25 (which is 5 squared) and 36 (which is 6 squared). These numbers are like little friends, all cozy and snug between 20 and 40. Just imagine them sitting there, all squared up and content.
10, 20, and 30 all have factors of 2 and 5
40 and 21 have no common prime factors
all the factors of 40 are 1, 2, 4, 5, 8, 10, 20, 40
The common factors for the numbers 25 95 and 40 are: 1, 5
The GCF of 25 and 40 is 5One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 25 are 1, 5, and 25.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The common factors are 1 and 5. Therefore, the greatest common factor is 5.
The greatest common factor (GCF) of 10, 25, and 40 is 5. To find the GCF, you need to determine the factors of each number and then identify the largest factor that is common to all three numbers. The factors of 10 are 1, 2, 5, and 10. The factors of 25 are 1, 5, 25. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The largest factor that is common to all three numbers is 5, making it the greatest common factor.
To work this out, you have to split the numbers into the product of their prime factors: 25 = 5x5 40 = 2x2x2x5 The next step is to identify any common factors. In this case, both numbers have a 5 as a prime factor. Thus the HCF of 25 and 40 is 5.
These numbers between 1 and 40 have an odd number of factors: 4, 9, 16, 25, 36.
The prime numbers (factors) of 40 are: 2 and 5
The greatest common factor (GCF) of 15, 25, and 40 is 5. To find the GCF, you need to determine the factors of each number and identify the largest factor that is common to all three numbers. The factors of 15 are 1, 3, 5, and 15. The factors of 25 are 1, 5, and 25. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The largest factor that is common to all three numbers is 5, making it the greatest common factor.
All of the numbers between 40 and 50 can be factors. The common factors of 40 and 50 are 1, 2, 5 and 10.
All numbers have factors.
The squares of all primes have exactly 3 factors. The squares of primes under 40 are 4 (1, 2, and 4), 9 (1, 3, and 9), and 25 (1, 5, and 25).
Numbers with three factors are squares of primes: 4, 9, 25
trick question, the number zero is in the list, therefore there is no common factors between all of these numbers
