Calculate the LCM of 390,284,411,416

Given numbers are 390,284,411,416

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

The LCM of 390,284,411,416 is 60696480.

Find LCM of 390,284,411,416 with Prime Factorization


2 390, 284, 411, 416
2 195, 142, 411, 208
3 195, 71, 411, 104
13 65, 71, 137, 104
5, 71, 137, 8

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

2 x 2 x 3 x 13 x 5 x 71 x 137 x 8 = 60696480

Therefore, the lowest common multiple of 390,284,411,416 is 60696480.

LCM Formula to Find Lowest Common Multiple of 390,284,411,416

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 284 x 411 x 416 = 18937301760

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

284 : 1, 2, 4, 71, 142, 284

411 : 1, 3, 137, 411

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,284,411,416, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

284:2x 2x 71

411:3x 137

416:2x 2x 2x 2x 2x 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 2x 3x 13 = 312

Therefore, the value for common factors is 312.

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 = 18937301760/(1x312)

LCM = 18937301760/312

LCM = 60696480

Thus, we can understand that the LCM of 390,284,411,416 is 60696480.
