Yes.
Correct. 5 and 2 are factors of 10, and will be factors of any number having 10 as a factor.
Any number that has another number for a factor has that number's factors as factors as well. Since 5 is a factor of 10, all multiples of 10 have 5 as a factor.
Every such number has.
the number 10 is a factor of any number that ends with zero
Because 10 is a factor of 20 and 40. So any number which divides 10 evenly divides the factor of 20 or 40 evenly
No, 10 is not a factor of either 15 or 25. Any number for which 10 is a factor will end in 0. Both 15 and 25 have 5 as a factor, but not 10.
The greatest sommon factor of 10 -2 and 14 is 2.
The GCF means it's a factor of both numbers. 10 is not a factor of 57.
Any multiple of 40.
The highest factor of any number is the number itself. The GCF of 20 and 50 is 10.
Any number to the first power is the number itself.
Any number is a factor and a multiple of itself. Other factors are less than the number, other multiples are more. 5 is a factor of 10. 10 is a multiple of 5.
