Given numbers are 254,974,731,390,397

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

The LCM of 254,974,731,390,397 is 7000114969770.

Find LCM of 254,974,731,390,397 with Prime Factorization

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

2 x 127 x 487 x 731 x 195 x 397 = 7000114969770

Therefore, the lowest common multiple of 254,974,731,390,397 is 7000114969770.

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.

254 x 974 x 731 x 390 x 397 = 28000459879080

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.

254 : 1, 2, 127, 254

974 : 1, 2, 487, 974

731 : 1, 17, 43, 731

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,974,731,390,397, is 1.

Now, the common factors can be found like this.

254:2x 127

974:2x 487

731:17x 43

390:2x 3x 5x 13

397:397

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 28000459879080/(1x4)

LCM = 28000459879080/4

LCM = 7000114969770

Thus, we can understand that the LCM of 254,974,731,390,397 is 7000114969770.
