Calculate the LCM of 809,694,694,742

Given numbers are 809,694,694,742

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

The LCM of 809,694,694,742 is 208296466.

Find LCM of 809,694,694,742 with Prime Factorization


2 809, 694, 694, 742
347 809, 347, 347, 371
809, 1, 1, 371

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

2 x 347 x 809 x 1 x 1 x 371 = 208296466

Therefore, the lowest common multiple of 809,694,694,742 is 208296466.

LCM Formula to Find Lowest Common Multiple of 809,694,694,742

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.

809 x 694 x 694 x 742 = 289115494808

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.

809 : 1, 809

694 : 1, 2, 347, 694

694 : 1, 2, 347, 694

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,694,694,742, is 1.

Now, the common factors can be found like this.

809:809

694:2x 347

694:2x 347

742:2x 7x 53

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 347 = 1388

Therefore, the value for common factors is 1388.

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 = 289115494808/(1x1388)

LCM = 289115494808/1388

LCM = 208296466

Thus, we can understand that the LCM of 809,694,694,742 is 208296466.
