Given numbers are 302,503,390,428

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

The LCM of 302,503,390,428 is 6339037380.

Find LCM of 302,503,390,428 with Prime Factorization

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

2 x 151 x 503 x 195 x 214 = 6339037380

Therefore, the lowest common multiple of 302,503,390,428 is 6339037380.

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.

302 x 503 x 390 x 428 = 25356149520

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.

302 : 1, 2, 151, 302

503 : 1, 503

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

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 302,503,390,428, is 1.

Now, the common factors can be found like this.

302:2x 151

503:503

390:2x 3x 5x 13

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 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 = 25356149520/(1x4)

LCM = 25356149520/4

LCM = 6339037380

Thus, we can understand that the LCM of 302,503,390,428 is 6339037380.
