Given numbers are 279,176,638,305

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

The LCM of 279,176,638,305 is 434324880.

Find LCM of 279,176,638,305 with Prime Factorization

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

2 x 11 x 279 x 8 x 29 x 305 = 434324880

Therefore, the lowest common multiple of 279,176,638,305 is 434324880.

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.

279 x 176 x 638 x 305 = 9555147360

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.

279 : 1, 3, 9, 31, 93, 279

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

638 : 1, 2, 11, 22, 29, 58, 319, 638

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,176,638,305, is 1.

Now, the common factors can be found like this.

279:3x 3x 31

176:2x 2x 2x 2x 11

638:2x 11x 29

305:5x 61

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 9555147360/(1x22)

LCM = 9555147360/22

LCM = 434324880

Thus, we can understand that the LCM of 279,176,638,305 is 434324880.
