Given numbers are 507,128,210

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

The LCM of 507,128,210 is 2271360.

Find LCM of 507,128,210 with Prime Factorization

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

2 x 3 x 169 x 64 x 35 = 2271360

Therefore, the lowest common multiple of 507,128,210 is 2271360.

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.

507 x 128 x 210 = 13628160

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.

507 : 1, 3, 13, 39, 169, 507

128 : 1, 2, 4, 8, 16, 32, 64, 128

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,128,210, is 1.

Now, the common factors can be found like this.

507:3x 13x 13

128:2x 2x 2x 2x 2x 2x 2

210:2x 3x 5x 7

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 = 13628160/(1x6)

LCM = 13628160/6

LCM = 2271360

Thus, we can understand that the LCM of 507,128,210 is 2271360.
