Given numbers are 390,339,422,371

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

The LCM of 390,339,422,371 is 3449843670.

Find LCM of 390,339,422,371 with Prime Factorization

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

2 x 3 x 65 x 113 x 211 x 371 = 3449843670

Therefore, the lowest common multiple of 390,339,422,371 is 3449843670.

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.

390 x 339 x 422 x 371 = 20699062020

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.

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

339 : 1, 3, 113, 339

422 : 1, 2, 211, 422

371 : 1, 7, 53, 371

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,339,422,371, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

339:3x 113

422:2x 211

371:7x 53

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 = 20699062020/(1x6)

LCM = 20699062020/6

LCM = 3449843670

Thus, we can understand that the LCM of 390,339,422,371 is 3449843670.
