Find LCM of 143,702,394,981 with Prime Factorization


2 143, 702, 394, 981
3 143, 351, 197, 981
3 143, 117, 197, 327
13 143, 39, 197, 109
11, 3, 197, 109

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

2 x 3 x 3 x 13 x 11 x 3 x 197 x 109 = 165814506

Therefore, the lowest common multiple of 143,702,394,981 is 165814506.

LCM Formula to Find Lowest Common Multiple of 143,702,394,981

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.

143 x 702 x 394 x 981 = 38800594404

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.

143 : 1, 11, 13, 143

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

394 : 1, 2, 197, 394

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,702,394,981, is 1.

Now, the common factors can be found like this.

143:11x 13

702:2x 3x 3x 3x 13

394:2x 197

981:3x 3x 109

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 13 = 234

Therefore, the value for common factors is 234.

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 = 38800594404/(1x234)

LCM = 38800594404/234

LCM = 165814506

Thus, we can understand that the LCM of 143,702,394,981 is 165814506.
