Given numbers are 642,411,694,251

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

The LCM of 642,411,694,251 is 7660529538.

Find LCM of 642,411,694,251 with Prime Factorization

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

2 x 3 x 107 x 137 x 347 x 251 = 7660529538

Therefore, the lowest common multiple of 642,411,694,251 is 7660529538.

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.

642 x 411 x 694 x 251 = 45963177228

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

411 : 1, 3, 137, 411

694 : 1, 2, 347, 694

251 : 1, 251

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,411,694,251, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

411:3x 137

694:2x 347

251:251

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 45963177228/(1x6)

LCM = 45963177228/6

LCM = 7660529538

Thus, we can understand that the LCM of 642,411,694,251 is 7660529538.
