Given numbers are 634,640,230,276

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

The LCM of 634,640,230,276 is 13998720.

Find LCM of 634,640,230,276 with Prime Factorization

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

2 x 2 x 5 x 23 x 317 x 32 x 1 x 3 = 13998720

Therefore, the lowest common multiple of 634,640,230,276 is 13998720.

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.

634 x 640 x 230 x 276 = 25757644800

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.

634 : 1, 2, 317, 634

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

230 : 1, 2, 5, 10, 23, 46, 115, 230

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,640,230,276, is 2.

Now, the common factors can be found like this.

634:2x 317

640:2x 2x 2x 2x 2x 2x 2x 5

230:2x 5x 23

276:2x 2x 3x 23

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 2x 5x 23 = 920

Therefore, the value for common factors is 920.

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 = 25757644800/(2x920)

LCM = 25757644800/1840

LCM = 13998720

Thus, we can understand that the LCM of 634,640,230,276 is 13998720.
