Calculate the LCM of 143,286,858,661

Given numbers are 143,286,858,661

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 143,286,858,661 is 567138.

Find LCM of 143,286,858,661 with Prime Factorization


2 143, 286, 858, 661
11 143, 143, 429, 661
13 13, 13, 39, 661
1, 1, 3, 661

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

2 x 11 x 13 x 1 x 1 x 3 x 661 = 567138

Therefore, the lowest common multiple of 143,286,858,661 is 567138.

LCM Formula to Find Lowest Common Multiple of 143,286,858,661

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 286 x 858 x 661 = 23194809924

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

286 : 1, 2, 11, 13, 22, 26, 143, 286

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,286,858,661, is 1.

Now, the common factors can be found like this.

143:11x 13

286:2x 11x 13

858:2x 3x 11x 13

661:661

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

2x 11x 11x 13x 13 = 40898

Therefore, the value for common factors is 40898.

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 = 23194809924/(1x40898)

LCM = 23194809924/40898

LCM = 567138

Thus, we can understand that the LCM of 143,286,858,661 is 567138.
