Calculate the LCM of 451,324,820,191

Given numbers are 451,324,820,191

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

The LCM of 451,324,820,191 is 139548420.

Find LCM of 451,324,820,191 with Prime Factorization


2 451, 324, 820, 191
2 451, 162, 410, 191
41 451, 81, 205, 191
11, 81, 5, 191

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

2 x 2 x 41 x 11 x 81 x 5 x 191 = 139548420

Therefore, the lowest common multiple of 451,324,820,191 is 139548420.

LCM Formula to Find Lowest Common Multiple of 451,324,820,191

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.

451 x 324 x 820 x 191 = 22885940880

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.

451 : 1, 11, 41, 451

324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

191 : 1, 191

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,324,820,191, is 1.

Now, the common factors can be found like this.

451:11x 41

324:2x 2x 3x 3x 3x 3

820:2x 2x 5x 41

191:191

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

2x 2x 41 = 164

Therefore, the value for common factors is 164.

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 = 22885940880/(1x164)

LCM = 22885940880/164

LCM = 139548420

Thus, we can understand that the LCM of 451,324,820,191 is 139548420.
