Given numbers are 102,455,247,917

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

The LCM of 102,455,247,917 is 115514490.

Find LCM of 102,455,247,917 with Prime Factorization

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

7 x 13 x 102 x 5 x 19 x 131 = 115514490

Therefore, the lowest common multiple of 102,455,247,917 is 115514490.

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.

102 x 455 x 247 x 917 = 10511818590

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.

102 : 1, 2, 3, 6, 17, 34, 51, 102

455 : 1, 5, 7, 13, 35, 65, 91, 455

247 : 1, 13, 19, 247

917 : 1, 7, 131, 917

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,455,247,917, is 1.

Now, the common factors can be found like this.

102:2x 3x 17

455:5x 7x 13

247:13x 19

917:7x 131

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7x 13 = 91

Therefore, the value for common factors is 91.

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 = 10511818590/(1x91)

LCM = 10511818590/91

LCM = 115514490

Thus, we can understand that the LCM of 102,455,247,917 is 115514490.
