Calculate the LCM of 381,440,141,803

Given numbers are 381,440,141,803

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

The LCM of 381,440,141,803 is 575172840.

Find LCM of 381,440,141,803 with Prime Factorization


3 381, 440, 141, 803
11 127, 440, 47, 803
127, 40, 47, 73

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

3 x 11 x 127 x 40 x 47 x 73 = 575172840

Therefore, the lowest common multiple of 381,440,141,803 is 575172840.

LCM Formula to Find Lowest Common Multiple of 381,440,141,803

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 440 x 141 x 803 = 18980703720

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

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

141 : 1, 3, 47, 141

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,440,141,803, is 1.

Now, the common factors can be found like this.

381:3x 127

440:2x 2x 2x 5x 11

141:3x 47

803:11x 73

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

3x 11 = 33

Therefore, the value for common factors is 33.

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 = 18980703720/(1x33)

LCM = 18980703720/33

LCM = 575172840

Thus, we can understand that the LCM of 381,440,141,803 is 575172840.
