Given numbers are 642,635,245,559

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

The LCM of 642,635,245,559 is 11166488970.

Find LCM of 642,635,245,559 with Prime Factorization

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

5 x 642 x 127 x 49 x 559 = 11166488970

Therefore, the lowest common multiple of 642,635,245,559 is 11166488970.

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 635 x 245 x 559 = 55832444850

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

635 : 1, 5, 127, 635

245 : 1, 5, 7, 35, 49, 245

559 : 1, 13, 43, 559

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,635,245,559, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

635:5x 127

245:5x 7x 7

559:13x 43

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

5 = 5

Therefore, the value for common factors is 5.

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 = 55832444850/(1x5)

LCM = 55832444850/5

LCM = 11166488970

Thus, we can understand that the LCM of 642,635,245,559 is 11166488970.
