Given numbers are 727,622,638,490,521

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

The LCM of 727,622,638,490,521 is 18412776698470.

Find LCM of 727,622,638,490,521 with Prime Factorization

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

2 x 727 x 311 x 319 x 245 x 521 = 18412776698470

Therefore, the lowest common multiple of 727,622,638,490,521 is 18412776698470.

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.

727 x 622 x 638 x 490 x 521 = 73651106793880

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.

727 : 1, 727

622 : 1, 2, 311, 622

638 : 1, 2, 11, 22, 29, 58, 319, 638

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,622,638,490,521, is 1.

Now, the common factors can be found like this.

727:727

622:2x 311

638:2x 11x 29

490:2x 5x 7x 7

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 73651106793880/(1x4)

LCM = 73651106793880/4

LCM = 18412776698470

Thus, we can understand that the LCM of 727,622,638,490,521 is 18412776698470.
