Is 10 a factor of 15 or 25?
NO!! '10' is a factor of numbers ending in '0' e.g. 1000000. '15' & '25' both end in '5' 10,15, & 25, have a factor of '5' .
What is the common factor of 10 and 25?
10= 1, 2, 5, 10 25= 1, 5, 25 Highest Common Factor= 5 Lowest Common Factor= 1
How do you determine 12 and 25 are relatively prime?
Two numbers are relatively prime if the only factor they have in common is 1. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 25 are 1, 5, and 10. The only factor they have in common is 1, so they are relatively prime.
What is the least common factor of 12 and 50?
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 50 are 1, 2, 5, 10, 25, and 50. The common factors are 1 and 2. Therefore, the least (smallest) common factor is 1.
What is the greatest common factor of 10 25 and 40?
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.
