Given numbers are 520,396,308,620

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

The LCM of 520,396,308,620 is 11171160.

Find LCM of 520,396,308,620 with Prime Factorization

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

2 x 2 x 5 x 11 x 26 x 9 x 7 x 31 = 11171160

Therefore, the lowest common multiple of 520,396,308,620 is 11171160.

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.

520 x 396 x 308 x 620 = 39322483200

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,396,308,620, is 4.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

396:2x 2x 3x 3x 11

308:2x 2x 7x 11

620:2x 2x 5x 31

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 2x 5x 11 = 880

Therefore, the value for common factors is 880.

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 = 39322483200/(4x880)

LCM = 39322483200/3520

LCM = 11171160

Thus, we can understand that the LCM of 520,396,308,620 is 11171160.
