Given numbers are 115,101,875,391,780

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

The LCM of 115,101,875,391,780 is 5390521500.

Find LCM of 115,101,875,391,780 with Prime Factorization

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

5 x 23 x 1 x 101 x 175 x 17 x 156 = 5390521500

Therefore, the lowest common multiple of 115,101,875,391,780 is 5390521500.

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.

115 x 101 x 875 x 391 x 780 = 3099549862500

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.

115 : 1, 5, 23, 115

101 : 1, 101

875 : 1, 5, 7, 25, 35, 125, 175, 875

391 : 1, 17, 23, 391

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 115,101,875,391,780, is 1.

Now, the common factors can be found like this.

115:5x 23

101:101

875:5x 5x 5x 7

391:17x 23

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.

5x 5x 23 = 575

Therefore, the value for common factors is 575.

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 = 3099549862500/(1x575)

LCM = 3099549862500/575

LCM = 5390521500

Thus, we can understand that the LCM of 115,101,875,391,780 is 5390521500.
