Given numbers are 350,955,720,821

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

The LCM of 350,955,720,821 is 3951637200.

Find LCM of 350,955,720,821 with Prime Factorization

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

2 x 5 x 35 x 191 x 72 x 821 = 3951637200

Therefore, the lowest common multiple of 350,955,720,821 is 3951637200.

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 955 x 720 x 821 = 197581860000

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

955 : 1, 5, 191, 955

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 350,955,720,821, is 1.

Now, the common factors can be found like this.

350:2x 5x 5x 7

955:5x 191

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 5x 5 = 50

Therefore, the value for common factors is 50.

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 = 197581860000/(1x50)

LCM = 197581860000/50

LCM = 3951637200

Thus, we can understand that the LCM of 350,955,720,821 is 3951637200.
