Given numbers are 654,694,521,729

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

The LCM of 654,694,521,729 is 28731031614.

Find LCM of 654,694,521,729 with Prime Factorization

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

2 x 3 x 109 x 347 x 521 x 243 = 28731031614

Therefore, the lowest common multiple of 654,694,521,729 is 28731031614.

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.

654 x 694 x 521 x 729 = 172386189684

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.

654 : 1, 2, 3, 6, 109, 218, 327, 654

694 : 1, 2, 347, 694

521 : 1, 521

729 : 1, 3, 9, 27, 81, 243, 729

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,694,521,729, is 1.

Now, the common factors can be found like this.

654:2x 3x 109

694:2x 347

521:521

729:3x 3x 3x 3x 3x 3

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 172386189684/(1x6)

LCM = 172386189684/6

LCM = 28731031614

Thus, we can understand that the LCM of 654,694,521,729 is 28731031614.
