Given numbers are 261,891,134,714,780

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

The LCM of 261,891,134,714,780 is 53563730220.

Find LCM of 261,891,134,714,780 with Prime Factorization

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

2 x 3 x 3 x 29 x 99 x 67 x 119 x 130 = 53563730220

Therefore, the lowest common multiple of 261,891,134,714,780 is 53563730220.

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.

261 x 891 x 134 x 714 x 780 = 17354648591280

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.

261 : 1, 3, 9, 29, 87, 261

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

134 : 1, 2, 67, 134

714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,891,134,714,780, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

891:3x 3x 3x 3x 11

134:2x 67

714:2x 3x 7x 17

780:2x 2x 3x 5x 13

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 3x 3x 3x 3 = 324

Therefore, the value for common factors is 324.

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 = 17354648591280/(1x324)

LCM = 17354648591280/324

LCM = 53563730220

Thus, we can understand that the LCM of 261,891,134,714,780 is 53563730220.
