Given numbers are 260,238,542,638

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

The LCM of 260,238,542,638 is 2674732060.

Find LCM of 260,238,542,638 with Prime Factorization

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

2 x 130 x 119 x 271 x 319 = 2674732060

Therefore, the lowest common multiple of 260,238,542,638 is 2674732060.

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.

260 x 238 x 542 x 638 = 21397856480

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.

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

238 : 1, 2, 7, 14, 17, 34, 119, 238

542 : 1, 2, 271, 542

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,238,542,638, is 2.

Now, the common factors can be found like this.

260:2x 2x 5x 13

238:2x 7x 17

542:2x 271

638:2x 11x 29

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 = 21397856480/(2x4)

LCM = 21397856480/8

LCM = 2674732060

Thus, we can understand that the LCM of 260,238,542,638 is 2674732060.
