Given numbers are 173,391,657,865

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

The LCM of 173,391,657,865 is 222207255.

Find LCM of 173,391,657,865 with Prime Factorization

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

173 x 1 x 391 x 657 x 5 = 222207255

Therefore, the lowest common multiple of 173,391,657,865 is 222207255.

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.

173 x 391 x 657 x 865 = 38441855115

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.

173 : 1, 173

391 : 1, 17, 23, 391

657 : 1, 3, 9, 73, 219, 657

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,391,657,865, is 1.

Now, the common factors can be found like this.

173:173

391:17x 23

657:3x 3x 73

865:5x 173

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

173 = 173

Therefore, the value for common factors is 173.

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 = 38441855115/(1x173)

LCM = 38441855115/173

LCM = 222207255

Thus, we can understand that the LCM of 173,391,657,865 is 222207255.
