Given numbers are 350,526,720,821

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

The LCM of 350,526,720,821 is 5441259600.

Find LCM of 350,526,720,821 with Prime Factorization

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

2 x 5 x 35 x 263 x 72 x 821 = 5441259600

Therefore, the lowest common multiple of 350,526,720,821 is 5441259600.

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.

350 x 526 x 720 x 821 = 108825192000

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.

350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350

526 : 1, 2, 263, 526

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

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 350,526,720,821, is 1.

Now, the common factors can be found like this.

350:2x 5x 5x 7

526:2x 263

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

821:821

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 5 = 20

Therefore, the value for common factors is 20.

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 = 108825192000/(1x20)

LCM = 108825192000/20

LCM = 5441259600

Thus, we can understand that the LCM of 350,526,720,821 is 5441259600.
