Given numbers are 48,13,39,21,913

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 48,13,39,21,913 is 3987984.

Find LCM of 48,13,39,21,913 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 13 x 16 x 1 x 1 x 7 x 913 = 3987984

Therefore, the lowest common multiple of 48,13,39,21,913 is 3987984.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

48 x 13 x 39 x 21 x 913 = 466594128

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

48 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

13 : 1, 13

39 : 1, 3, 13, 39

21 : 1, 3, 7, 21

913 : 1, 11, 83, 913

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 48,13,39,21,913, is 1.

Now, the common factors can be found like this.

48:2x 2x 2x 2x 3

13:13

39:3x 13

21:3x 7

913:11x 83

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3x 13 = 117

Therefore, the value for common factors is 117.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 466594128/(1x117)

LCM = 466594128/117

LCM = 3987984

Thus, we can understand that the LCM of 48,13,39,21,913 is 3987984.
