Given numbers are 407,530,221,430

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

The LCM of 407,530,221,430 is 2049892130.

Find LCM of 407,530,221,430 with Prime Factorization

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

2 x 5 x 407 x 53 x 221 x 43 = 2049892130

Therefore, the lowest common multiple of 407,530,221,430 is 2049892130.

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.

407 x 530 x 221 x 430 = 20498921300

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.

407 : 1, 11, 37, 407

530 : 1, 2, 5, 10, 53, 106, 265, 530

221 : 1, 13, 17, 221

430 : 1, 2, 5, 10, 43, 86, 215, 430

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,530,221,430, is 1.

Now, the common factors can be found like this.

407:11x 37

530:2x 5x 53

221:13x 17

430:2x 5x 43

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 20498921300/(1x10)

LCM = 20498921300/10

LCM = 2049892130

Thus, we can understand that the LCM of 407,530,221,430 is 2049892130.
