Given numbers are 45,91,13,67,839

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

The LCM of 45,91,13,67,839 is 230192235.

Find LCM of 45,91,13,67,839 with Prime Factorization

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

13 x 45 x 7 x 1 x 67 x 839 = 230192235

Therefore, the lowest common multiple of 45,91,13,67,839 is 230192235.

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.

45 x 91 x 13 x 67 x 839 = 2992499055

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.

45 : 1, 3, 5, 9, 15, 45

91 : 1, 7, 13, 91

13 : 1, 13

67 : 1, 67

839 : 1, 839

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 45,91,13,67,839, is 1.

Now, the common factors can be found like this.

45:3x 3x 5

91:7x 13

13:13

67:67

839:839

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

13 = 13

Therefore, the value for common factors is 13.

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 = 2992499055/(1x13)

LCM = 2992499055/13

LCM = 230192235

Thus, we can understand that the LCM of 45,91,13,67,839 is 230192235.
