Given numbers are 260,521,138,521

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

The LCM of 260,521,138,521 is 9346740.

Find LCM of 260,521,138,521 with Prime Factorization

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

2 x 521 x 130 x 1 x 69 x 1 = 9346740

Therefore, the lowest common multiple of 260,521,138,521 is 9346740.

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 521 x 138 x 521 = 9739303080

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

521 : 1, 521

138 : 1, 2, 3, 6, 23, 46, 69, 138

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,521,138,521, is 1.

Now, the common factors can be found like this.

260:2x 2x 5x 13

521:521

138:2x 3x 23

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 521 = 1042

Therefore, the value for common factors is 1042.

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 = 9739303080/(1x1042)

LCM = 9739303080/1042

LCM = 9346740

Thus, we can understand that the LCM of 260,521,138,521 is 9346740.
