Given numbers are 398,357,390,936

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

The LCM of 398,357,390,936 is 110827080.

Find LCM of 398,357,390,936 with Prime Factorization

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

2 x 3 x 13 x 199 x 119 x 5 x 12 = 110827080

Therefore, the lowest common multiple of 398,357,390,936 is 110827080.

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.

398 x 357 x 390 x 936 = 51867073440

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.

398 : 1, 2, 199, 398

357 : 1, 3, 7, 17, 21, 51, 119, 357

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

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,357,390,936, is 1.

Now, the common factors can be found like this.

398:2x 199

357:3x 7x 17

390:2x 3x 5x 13

936:2x 2x 2x 3x 3x 13

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 3x 3x 13 = 468

Therefore, the value for common factors is 468.

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 = 51867073440/(1x468)

LCM = 51867073440/468

LCM = 110827080

Thus, we can understand that the LCM of 398,357,390,936 is 110827080.
