Given numbers are 728,252,221,598,619

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

The LCM of 728,252,221,598,619 is 1585774008.

Find LCM of 728,252,221,598,619 with Prime Factorization

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

2 x 2 x 7 x 13 x 2 x 9 x 17 x 23 x 619 = 1585774008

Therefore, the lowest common multiple of 728,252,221,598,619 is 1585774008.

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.

728 x 252 x 221 x 598 x 619 = 15007765211712

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

221 : 1, 13, 17, 221

598 : 1, 2, 13, 23, 26, 46, 299, 598

619 : 1, 619

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,252,221,598,619, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

252:2x 2x 3x 3x 7

221:13x 17

598:2x 13x 23

619:619

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 2x 7x 13x 13 = 9464

Therefore, the value for common factors is 9464.

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 = 15007765211712/(1x9464)

LCM = 15007765211712/9464

LCM = 1585774008

Thus, we can understand that the LCM of 728,252,221,598,619 is 1585774008.
