Calculate the LCM of 105,821,804,402

Given numbers are 105,821,804,402

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

The LCM of 105,821,804,402 is 23102940.

Find LCM of 105,821,804,402 with Prime Factorization


2 105, 821, 804, 402
3 105, 821, 402, 201
67 35, 821, 134, 67
35, 821, 2, 1

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

2 x 3 x 67 x 35 x 821 x 2 x 1 = 23102940

Therefore, the lowest common multiple of 105,821,804,402 is 23102940.

LCM Formula to Find Lowest Common Multiple of 105,821,804,402

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.

105 x 821 x 804 x 402 = 27862145640

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.

105 : 1, 3, 5, 7, 15, 21, 35, 105

821 : 1, 821

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,821,804,402, is 1.

Now, the common factors can be found like this.

105:3x 5x 7

821:821

804:2x 2x 3x 67

402:2x 3x 67

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

2x 3x 3x 67 = 1206

Therefore, the value for common factors is 1206.

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 = 27862145640/(1x1206)

LCM = 27862145640/1206

LCM = 23102940

Thus, we can understand that the LCM of 105,821,804,402 is 23102940.
