Find LCM of 429,847,894,840 with Prime Factorization


2 429, 847, 894, 840
3 429, 847, 447, 420
7 143, 847, 149, 140
11 143, 121, 149, 20
13, 11, 149, 20

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

2 x 3 x 7 x 11 x 13 x 11 x 149 x 20 = 196876680

Therefore, the lowest common multiple of 429,847,894,840 is 196876680.

LCM Formula to Find Lowest Common Multiple of 429,847,894,840

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.

429 x 847 x 894 x 840 = 272871078480

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.

429 : 1, 3, 11, 13, 33, 39, 143, 429

847 : 1, 7, 11, 77, 121, 847

894 : 1, 2, 3, 6, 149, 298, 447, 894

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,847,894,840, is 1.

Now, the common factors can be found like this.

429:3x 11x 13

847:7x 11x 11

894:2x 3x 149

840:2x 2x 2x 3x 5x 7

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 3x 7x 11 = 1386

Therefore, the value for common factors is 1386.

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 = 272871078480/(1x1386)

LCM = 272871078480/1386

LCM = 196876680

Thus, we can understand that the LCM of 429,847,894,840 is 196876680.
