Given numbers are 425,398,328,428

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

The LCM of 425,398,328,428 is 2968244200.

Find LCM of 425,398,328,428 with Prime Factorization

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

2 x 2 x 425 x 199 x 82 x 107 = 2968244200

Therefore, the lowest common multiple of 425,398,328,428 is 2968244200.

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.

425 x 398 x 328 x 428 = 23745953600

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.

425 : 1, 5, 17, 25, 85, 425

398 : 1, 2, 199, 398

328 : 1, 2, 4, 8, 41, 82, 164, 328

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 425,398,328,428, is 1.

Now, the common factors can be found like this.

425:5x 5x 17

398:2x 199

328:2x 2x 2x 41

428:2x 2x 107

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 23745953600/(1x8)

LCM = 23745953600/8

LCM = 2968244200

Thus, we can understand that the LCM of 425,398,328,428 is 2968244200.
