Given numbers are 268,487,470,987

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

The LCM of 268,487,470,987 is 644096460.

Find LCM of 268,487,470,987 with Prime Factorization

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

2 x 47 x 134 x 487 x 5 x 21 = 644096460

Therefore, the lowest common multiple of 268,487,470,987 is 644096460.

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.

268 x 487 x 470 x 987 = 60545067240

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.

268 : 1, 2, 4, 67, 134, 268

487 : 1, 487

470 : 1, 2, 5, 10, 47, 94, 235, 470

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,487,470,987, is 1.

Now, the common factors can be found like this.

268:2x 2x 67

487:487

470:2x 5x 47

987:3x 7x 47

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

2x 47 = 94

Therefore, the value for common factors is 94.

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 = 60545067240/(1x94)

LCM = 60545067240/94

LCM = 644096460

Thus, we can understand that the LCM of 268,487,470,987 is 644096460.
