The factors of 49 are 1, 7 and 49. The factors of a given number are those numbers that divide into it evenly leaving no remainder. One and the number itself, 49 in this case, are always factors.
Know MoreThe number 49 is a square, which means that a number multiplied by itself yields 49, and that number is seven. Seven is called the square root of 49. Seven is also a prime number, which means it is evenly divisible by only one and itself. The prime factorization of 49 therefore is 7 x 7 or 7^2. Prime factorization of a number involves finding the prime numbers that multiply together to yield that number.

Full Answer >The factors of 27 are one, three, nine and 27. The factors of a particular number are those numbers that divide evenly into it. One and the number itself are always factors of any given number.
Full Answer >The factors of 26 are one, two, 13 and 26. One and the number itself, in this case 26, are always factors. Since 26 is an even number, which means that it ends in zero, two, four, six or eight, it's evenly divisible by two. Two times 13 equals 26.
Full Answer >The factors of 40 are 1, 2, 4, 5, 8, 10, 20 and 40. These are the numbers that when multiplied together give the product of 40—1 x 40 = 40, 2 x 20 = 40, 4 x 10 = 40 and 5 x 8 = 40.
