Given numbers are 428,566,478,430

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

The LCM of 428,566,478,430 is 6223956740.

Find LCM of 428,566,478,430 with Prime Factorization

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

2 x 214 x 283 x 239 x 215 = 6223956740

Therefore, the lowest common multiple of 428,566,478,430 is 6223956740.

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.

428 x 566 x 478 x 430 = 49791653920

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.

428 : 1, 2, 4, 107, 214, 428

566 : 1, 2, 283, 566

478 : 1, 2, 239, 478

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,566,478,430, is 2.

Now, the common factors can be found like this.

428:2x 2x 107

566:2x 283

478:2x 239

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 2 = 4

Therefore, the value for common factors is 4.

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 = 49791653920/(2x4)

LCM = 49791653920/8

LCM = 6223956740

Thus, we can understand that the LCM of 428,566,478,430 is 6223956740.
