Given numbers are 397,520,791,438,886

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

The LCM of 397,520,791,438,886 is 15842297878680.

Find LCM of 397,520,791,438,886 with Prime Factorization

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

2 x 397 x 260 x 791 x 219 x 443 = 15842297878680

Therefore, the lowest common multiple of 397,520,791,438,886 is 15842297878680.

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.

397 x 520 x 791 x 438 x 886 = 63369191514720

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.

397 : 1, 397

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

791 : 1, 7, 113, 791

438 : 1, 2, 3, 6, 73, 146, 219, 438

886 : 1, 2, 443, 886

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,520,791,438,886, is 1.

Now, the common factors can be found like this.

397:397

520:2x 2x 2x 5x 13

791:7x 113

438:2x 3x 73

886:2x 443

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 63369191514720/(1x4)

LCM = 63369191514720/4

LCM = 15842297878680

Thus, we can understand that the LCM of 397,520,791,438,886 is 15842297878680.
