Given numbers are 670,209,473,815

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

The LCM of 670,209,473,815 is 981470270.

Find LCM of 670,209,473,815 with Prime Factorization

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

5 x 11 x 134 x 19 x 43 x 163 = 981470270

Therefore, the lowest common multiple of 670,209,473,815 is 981470270.

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.

670 x 209 x 473 x 815 = 53980864850

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.

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

209 : 1, 11, 19, 209

473 : 1, 11, 43, 473

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,209,473,815, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

209:11x 19

473:11x 43

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 11 = 55

Therefore, the value for common factors is 55.

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 = 53980864850/(1x55)

LCM = 53980864850/55

LCM = 981470270

Thus, we can understand that the LCM of 670,209,473,815 is 981470270.
