Given numbers are 395,771,538,520

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

The LCM of 395,771,538,520 is 8519950920.

Find LCM of 395,771,538,520 with Prime Factorization

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

2 x 5 x 79 x 771 x 269 x 52 = 8519950920

Therefore, the lowest common multiple of 395,771,538,520 is 8519950920.

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.

395 x 771 x 538 x 520 = 85199509200

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.

395 : 1, 5, 79, 395

771 : 1, 3, 257, 771

538 : 1, 2, 269, 538

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,771,538,520, is 1.

Now, the common factors can be found like this.

395:5x 79

771:3x 257

538:2x 269

520:2x 2x 2x 5x 13

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 = 85199509200/(1x10)

LCM = 85199509200/10

LCM = 8519950920

Thus, we can understand that the LCM of 395,771,538,520 is 8519950920.
