Given numbers are 635,121,315,815

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

The LCM of 635,121,315,815 is 789018615.

Find LCM of 635,121,315,815 with Prime Factorization

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

5 x 127 x 121 x 63 x 163 = 789018615

Therefore, the lowest common multiple of 635,121,315,815 is 789018615.

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.

635 x 121 x 315 x 815 = 19725465375

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.

635 : 1, 5, 127, 635

121 : 1, 11, 121

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,121,315,815, is 1.

Now, the common factors can be found like this.

635:5x 127

121:11x 11

315:3x 3x 5x 7

815:5x 163

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 19725465375/(1x25)

LCM = 19725465375/25

LCM = 789018615

Thus, we can understand that the LCM of 635,121,315,815 is 789018615.
