Given numbers are 473,815,644,665

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

The LCM of 473,815,644,665 is 4716916820.

Find LCM of 473,815,644,665 with Prime Factorization

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

5 x 7 x 473 x 163 x 92 x 19 = 4716916820

Therefore, the lowest common multiple of 473,815,644,665 is 4716916820.

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.

473 x 815 x 644 x 665 = 165092088700

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.

473 : 1, 11, 43, 473

815 : 1, 5, 163, 815

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,815,644,665, is 1.

Now, the common factors can be found like this.

473:11x 43

815:5x 163

644:2x 2x 7x 23

665:5x 7x 19

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

5x 7 = 35

Therefore, the value for common factors is 35.

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 = 165092088700/(1x35)

LCM = 165092088700/35

LCM = 4716916820

Thus, we can understand that the LCM of 473,815,644,665 is 4716916820.
