Given numbers are 142,639,971,284

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

The LCM of 142,639,971,284 is 2481876.

Find LCM of 142,639,971,284 with Prime Factorization

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

2 x 71 x 1 x 9 x 971 x 2 = 2481876

Therefore, the lowest common multiple of 142,639,971,284 is 2481876.

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.

142 x 639 x 971 x 284 = 25022273832

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.

142 : 1, 2, 71, 142

639 : 1, 3, 9, 71, 213, 639

971 : 1, 971

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,639,971,284, is 1.

Now, the common factors can be found like this.

142:2x 71

639:3x 3x 71

971:971

284:2x 2x 71

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

2x 71x 71 = 10082

Therefore, the value for common factors is 10082.

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 = 25022273832/(1x10082)

LCM = 25022273832/10082

LCM = 2481876

Thus, we can understand that the LCM of 142,639,971,284 is 2481876.
