The LCM of 806,129,744,814 is 169269672.

Find LCM of 806,129,744,814 with Prime Factorization


2 806, 129, 744, 814
3 403, 129, 372, 407
31 403, 43, 124, 407
13, 43, 4, 407

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

2 x 3 x 31 x 13 x 43 x 4 x 407 = 169269672

Therefore, the lowest common multiple of 806,129,744,814 is 169269672.

LCM Formula to Find Lowest Common Multiple of 806,129,744,814

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.

806 x 129 x 744 x 814 = 62968317984

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.

806 : 1, 2, 13, 26, 31, 62, 403, 806

129 : 1, 3, 43, 129

744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744

814 : 1, 2, 11, 22, 37, 74, 407, 814

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,129,744,814, is 1.

Now, the common factors can be found like this.

806:2x 13x 31

129:3x 43

744:2x 2x 2x 3x 31

814:2x 11x 37

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 3x 31 = 372

Therefore, the value for common factors is 372.

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 = 62968317984/(1x372)

LCM = 62968317984/372

LCM = 169269672

Thus, we can understand that the LCM of 806,129,744,814 is 169269672.
