Given numbers are 7,670,135,815

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

The LCM of 7,670,135,815 is 20640690.

Find LCM of 7,670,135,815 with Prime Factorization

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

5 x 7 x 134 x 27 x 163 = 20640690

Therefore, the lowest common multiple of 7,670,135,815 is 20640690.

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.

7 x 670 x 135 x 815 = 516017250

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.

7 : 1, 7

670 : 1, 2, 5, 10, 67, 134, 335, 670

135 : 1, 3, 5, 9, 15, 27, 45, 135

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,670,135,815, is 1.

Now, the common factors can be found like this.

7:7

670:2x 5x 67

135:3x 3x 3x 5

815:5x 163

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 516017250/(1x25)

LCM = 516017250/25

LCM = 20640690

Thus, we can understand that the LCM of 7,670,135,815 is 20640690.
