Given numbers are 697,581,166,391

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

The LCM of 697,581,166,391 is 18628022.

Find LCM of 697,581,166,391 with Prime Factorization

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

17 x 83 x 41 x 7 x 2 x 23 = 18628022

Therefore, the lowest common multiple of 697,581,166,391 is 18628022.

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.

697 x 581 x 166 x 391 = 26284139042

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.

697 : 1, 17, 41, 697

581 : 1, 7, 83, 581

166 : 1, 2, 83, 166

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,581,166,391, is 1.

Now, the common factors can be found like this.

697:17x 41

581:7x 83

166:2x 83

391:17x 23

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

17x 83 = 1411

Therefore, the value for common factors is 1411.

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 = 26284139042/(1x1411)

LCM = 26284139042/1411

LCM = 18628022

Thus, we can understand that the LCM of 697,581,166,391 is 18628022.
