Given numbers are 839,310,520,721

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

The LCM of 839,310,520,721 is 9751294280.

Find LCM of 839,310,520,721 with Prime Factorization

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

2 x 5 x 839 x 31 x 52 x 721 = 9751294280

Therefore, the lowest common multiple of 839,310,520,721 is 9751294280.

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.

839 x 310 x 520 x 721 = 97512942800

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.

839 : 1, 839

310 : 1, 2, 5, 10, 31, 62, 155, 310

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

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 839,310,520,721, is 1.

Now, the common factors can be found like this.

839:839

310:2x 5x 31

520:2x 2x 2x 5x 13

721:7x 103

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 = 97512942800/(1x10)

LCM = 97512942800/10

LCM = 9751294280

Thus, we can understand that the LCM of 839,310,520,721 is 9751294280.
