Given numbers are 520,176,720,533

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

The LCM of 520,176,720,533 is 4221360.

Find LCM of 520,176,720,533 with Prime Factorization

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

2 x 2 x 2 x 2 x 5 x 13 x 1 x 11 x 9 x 41 = 4221360

Therefore, the lowest common multiple of 520,176,720,533 is 4221360.

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 176 x 720 x 533 = 35121715200

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

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

533 : 1, 13, 41, 533

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,176,720,533, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

176:2x 2x 2x 2x 11

720:2x 2x 2x 2x 3x 3x 5

533:13x 41

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 2x 2x 2x 5x 13 = 8320

Therefore, the value for common factors is 8320.

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 = 35121715200/(1x8320)

LCM = 35121715200/8320

LCM = 4221360

Thus, we can understand that the LCM of 520,176,720,533 is 4221360.
