Given numbers are 217,715,837,578,173

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

The LCM of 217,715,837,578,173 is 418893364890.

Find LCM of 217,715,837,578,173 with Prime Factorization

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

31 x 7 x 715 x 27 x 578 x 173 = 418893364890

Therefore, the lowest common multiple of 217,715,837,578,173 is 418893364890.

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.

217 x 715 x 837 x 578 x 173 = 12985694311590

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.

217 : 1, 7, 31, 217

715 : 1, 5, 11, 13, 55, 65, 143, 715

837 : 1, 3, 9, 27, 31, 93, 279, 837

578 : 1, 2, 17, 34, 289, 578

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,715,837,578,173, is 1.

Now, the common factors can be found like this.

217:7x 31

715:5x 11x 13

837:3x 3x 3x 31

578:2x 17x 17

173:173

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

31 = 31

Therefore, the value for common factors is 31.

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 = 12985694311590/(1x31)

LCM = 12985694311590/31

LCM = 418893364890

Thus, we can understand that the LCM of 217,715,837,578,173 is 418893364890.
