Given numbers are 251,169,987,655,855

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

The LCM of 251,169,987,655,855 is 1563125091255.

Find LCM of 251,169,987,655,855 with Prime Factorization

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

3 x 5 x 251 x 169 x 329 x 131 x 57 = 1563125091255

Therefore, the lowest common multiple of 251,169,987,655,855 is 1563125091255.

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.

251 x 169 x 987 x 655 x 855 = 23446876368825

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.

251 : 1, 251

169 : 1, 13, 169

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

655 : 1, 5, 131, 655

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,169,987,655,855, is 1.

Now, the common factors can be found like this.

251:251

169:13x 13

987:3x 7x 47

655:5x 131

855:3x 3x 5x 19

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 23446876368825/(1x15)

LCM = 23446876368825/15

LCM = 1563125091255

Thus, we can understand that the LCM of 251,169,987,655,855 is 1563125091255.
