Given numbers are 142,643,698,521

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

The LCM of 142,643,698,521 is 16602078674.

Find LCM of 142,643,698,521 with Prime Factorization

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

2 x 71 x 643 x 349 x 521 = 16602078674

Therefore, the lowest common multiple of 142,643,698,521 is 16602078674.

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 643 x 698 x 521 = 33204157348

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

643 : 1, 643

698 : 1, 2, 349, 698

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,643,698,521, is 1.

Now, the common factors can be found like this.

142:2x 71

643:643

698:2x 349

521:521

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 = 33204157348/(1x2)

LCM = 33204157348/2

LCM = 16602078674

Thus, we can understand that the LCM of 142,643,698,521 is 16602078674.
