Given numbers are 455,276,103,247

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

The LCM of 455,276,103,247 is 245760060.

Find LCM of 455,276,103,247 with Prime Factorization

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

13 x 35 x 276 x 103 x 19 = 245760060

Therefore, the lowest common multiple of 455,276,103,247 is 245760060.

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.

455 x 276 x 103 x 247 = 3194880780

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.

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

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

103 : 1, 103

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,276,103,247, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

276:2x 2x 3x 23

103:103

247:13x 19

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

13 = 13

Therefore, the value for common factors is 13.

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 = 3194880780/(1x13)

LCM = 3194880780/13

LCM = 245760060

Thus, we can understand that the LCM of 455,276,103,247 is 245760060.
