Calculate the LCM of 470,347,921,320

Given numbers are 470,347,921,320

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

The LCM of 470,347,921,320 is 4806588480.

Find LCM of 470,347,921,320 with Prime Factorization


2 470, 347, 921, 320
5 235, 347, 921, 160
47, 347, 921, 32

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

2 x 5 x 47 x 347 x 921 x 32 = 4806588480

Therefore, the lowest common multiple of 470,347,921,320 is 4806588480.

LCM Formula to Find Lowest Common Multiple of 470,347,921,320

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.

470 x 347 x 921 x 320 = 48065884800

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.

470 : 1, 2, 5, 10, 47, 94, 235, 470

347 : 1, 347

921 : 1, 3, 307, 921

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,347,921,320, is 1.

Now, the common factors can be found like this.

470:2x 5x 47

347:347

921:3x 307

320:2x 2x 2x 2x 2x 2x 5

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 48065884800/(1x10)

LCM = 48065884800/10

LCM = 4806588480

Thus, we can understand that the LCM of 470,347,921,320 is 4806588480.
