Given numbers are 681,142,334,807,644

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

The LCM of 681,142,334,807,644 is 1398814350612.

Find LCM of 681,142,334,807,644 with Prime Factorization

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

2 x 3 x 227 x 71 x 167 x 269 x 322 = 1398814350612

Therefore, the lowest common multiple of 681,142,334,807,644 is 1398814350612.

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.

681 x 142 x 334 x 807 x 644 = 16785772207344

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.

681 : 1, 3, 227, 681

142 : 1, 2, 71, 142

334 : 1, 2, 167, 334

807 : 1, 3, 269, 807

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,142,334,807,644, is 1.

Now, the common factors can be found like this.

681:3x 227

142:2x 71

334:2x 167

807:3x 269

644:2x 2x 7x 23

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 16785772207344/(1x12)

LCM = 16785772207344/12

LCM = 1398814350612

Thus, we can understand that the LCM of 681,142,334,807,644 is 1398814350612.
