Given numbers are 143,706,617,420

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

The LCM of 143,706,617,420 is 13081128060.

Find LCM of 143,706,617,420 with Prime Factorization

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

2 x 143 x 353 x 617 x 210 = 13081128060

Therefore, the lowest common multiple of 143,706,617,420 is 13081128060.

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 706 x 617 x 420 = 26162256120

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

706 : 1, 2, 353, 706

617 : 1, 617

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,706,617,420, is 1.

Now, the common factors can be found like this.

143:11x 13

706:2x 353

617:617

420:2x 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.

2 = 2

Therefore, the value for common factors is 2.

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 = 26162256120/(1x2)

LCM = 26162256120/2

LCM = 13081128060

Thus, we can understand that the LCM of 143,706,617,420 is 13081128060.
