Given numbers are 253,391,115,985

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

The LCM of 253,391,115,985 is 4236485.

Find LCM of 253,391,115,985 with Prime Factorization

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

5 x 23 x 11 x 17 x 1 x 197 = 4236485

Therefore, the lowest common multiple of 253,391,115,985 is 4236485.

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.

253 x 391 x 115 x 985 = 11205502825

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.

253 : 1, 11, 23, 253

391 : 1, 17, 23, 391

115 : 1, 5, 23, 115

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,391,115,985, is 1.

Now, the common factors can be found like this.

253:11x 23

391:17x 23

115:5x 23

985:5x 197

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

5x 23x 23 = 2645

Therefore, the value for common factors is 2645.

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 = 11205502825/(1x2645)

LCM = 11205502825/2645

LCM = 4236485

Thus, we can understand that the LCM of 253,391,115,985 is 4236485.
