1, 2, 191, 382
382 = 2 x 191
Three
no it does not and the smallest missing factor that would allow for divisibility is 13
(80,1)(40,2)(20,4)(16,5)(10,8)
It is: 7
Because if you divide a factor from the another number you will get the corresponding factor
22 is a multiple of 11. 22 is a factor of 44.
The greatest common factor is 2.
Factors are divisors. If you know the divisibility rules, you know that 80 is divisible by 1, 2, 4, 5 and 8. If you divide 80 by those numbers, you find the other half of the factor pairs.
You use divisibility rules t determine whether a particular number is (or is not) a factor of another number. If it is a factor, you can reduce the numbers involved to smaller numbers.You might want to find factors to simplify fractions or to add or subtract factions.
Those for 1, 2, 4, 5 and 8.
