Calculate the LCM of 381,398,205,802

Given numbers are 381,398,205,802

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

The LCM of 381,398,205,802 is 12465401790.

Find LCM of 381,398,205,802 with Prime Factorization


2 381, 398, 205, 802
381, 199, 205, 401

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

2 x 381 x 199 x 205 x 401 = 12465401790

Therefore, the lowest common multiple of 381,398,205,802 is 12465401790.

LCM Formula to Find Lowest Common Multiple of 381,398,205,802

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.

381 x 398 x 205 x 802 = 24930803580

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.

381 : 1, 3, 127, 381

398 : 1, 2, 199, 398

205 : 1, 5, 41, 205

802 : 1, 2, 401, 802

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,398,205,802, is 1.

Now, the common factors can be found like this.

381:3x 127

398:2x 199

205:5x 41

802:2x 401

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

2 = 2

Therefore, the value for common factors is 2.

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 = 24930803580/(1x2)

LCM = 24930803580/2

LCM = 12465401790

Thus, we can understand that the LCM of 381,398,205,802 is 12465401790.
