Given numbers are 391,694,805,671,651

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

The LCM of 391,694,805,671,651 is 592665628170.

Find LCM of 391,694,805,671,651 with Prime Factorization

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

7 x 23 x 17 x 694 x 5 x 671 x 93 = 592665628170

Therefore, the lowest common multiple of 391,694,805,671,651 is 592665628170.

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.

391 x 694 x 805 x 671 x 651 = 95419166135370

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.

391 : 1, 17, 23, 391

694 : 1, 2, 347, 694

805 : 1, 5, 7, 23, 35, 115, 161, 805

671 : 1, 11, 61, 671

651 : 1, 3, 7, 21, 31, 93, 217, 651

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,694,805,671,651, is 1.

Now, the common factors can be found like this.

391:17x 23

694:2x 347

805:5x 7x 23

671:11x 61

651:3x 7x 31

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 95419166135370/(1x161)

LCM = 95419166135370/161

LCM = 592665628170

Thus, we can understand that the LCM of 391,694,805,671,651 is 592665628170.
