Given numbers are 635,25,221

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

The LCM of 635,25,221 is 701675.

Find LCM of 635,25,221 with Prime Factorization

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

5 x 127 x 5 x 221 = 701675

Therefore, the lowest common multiple of 635,25,221 is 701675.

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 25 x 221 = 3508375

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

25 : 1, 5, 25

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,25,221, is 1.

Now, the common factors can be found like this.

635:5x 127

25:5x 5

221:13x 17

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 = 3508375/(1x5)

LCM = 3508375/5

LCM = 701675

Thus, we can understand that the LCM of 635,25,221 is 701675.
