The LCM of 455,806,338,161 is 8434790.

Find LCM of 455,806,338,161 with Prime Factorization


2 455, 806, 338, 161
7 455, 403, 169, 161
13 65, 403, 169, 23
5, 31, 13, 23

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

2 x 7 x 13 x 5 x 31 x 13 x 23 = 8434790

Therefore, the lowest common multiple of 455,806,338,161 is 8434790.

LCM Formula to Find Lowest Common Multiple of 455,806,338,161

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.

455 x 806 x 338 x 161 = 19956713140

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

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

338 : 1, 2, 13, 26, 169, 338

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,806,338,161, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

806:2x 13x 31

338:2x 13x 13

161:7x 23

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

2x 7x 13x 13 = 2366

Therefore, the value for common factors is 2366.

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 = 19956713140/(1x2366)

LCM = 19956713140/2366

LCM = 8434790

Thus, we can understand that the LCM of 455,806,338,161 is 8434790.
