The LCM of 819,806,255,418 is 902071170.

Find LCM of 819,806,255,418 with Prime Factorization


2 819, 806, 255, 418
3 819, 403, 255, 209
13 273, 403, 85, 209
21, 31, 85, 209

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

2 x 3 x 13 x 21 x 31 x 85 x 209 = 902071170

Therefore, the lowest common multiple of 819,806,255,418 is 902071170.

LCM Formula to Find Lowest Common Multiple of 819,806,255,418

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.

819 x 806 x 255 x 418 = 70361551260

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.

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

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

255 : 1, 3, 5, 15, 17, 51, 85, 255

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,806,255,418, is 1.

Now, the common factors can be found like this.

819:3x 3x 7x 13

806:2x 13x 31

255:3x 5x 17

418:2x 11x 19

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 13 = 78

Therefore, the value for common factors is 78.

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 = 70361551260/(1x78)

LCM = 70361551260/78

LCM = 902071170

Thus, we can understand that the LCM of 819,806,255,418 is 902071170.
