Calculate the LCM of 820,841,692

Given numbers are 820,841,692

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

The LCM of 820,841,692 is 119304260.

Find LCM of 820,841,692 with Prime Factorization


2 820, 841, 692
2 410, 841, 346
205, 841, 173

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

2 x 2 x 205 x 841 x 173 = 119304260

Therefore, the lowest common multiple of 820,841,692 is 119304260.

LCM Formula to Find Lowest Common Multiple of 820,841,692

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.

820 x 841 x 692 = 477217040

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.

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

841 : 1, 29, 841

692 : 1, 2, 4, 173, 346, 692

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,841,692, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

841:29x 29

692:2x 2x 173

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 = 477217040/(1x4)

LCM = 477217040/4

LCM = 119304260

Thus, we can understand that the LCM of 820,841,692 is 119304260.
