Given numbers are 397,838,431,986

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

The LCM of 397,838,431,986 is 70690119338.

Find LCM of 397,838,431,986 with Prime Factorization

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

2 x 397 x 419 x 431 x 493 = 70690119338

Therefore, the lowest common multiple of 397,838,431,986 is 70690119338.

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.

397 x 838 x 431 x 986 = 141380238676

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.

397 : 1, 397

838 : 1, 2, 419, 838

431 : 1, 431

986 : 1, 2, 17, 29, 34, 58, 493, 986

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,838,431,986, is 1.

Now, the common factors can be found like this.

397:397

838:2x 419

431:431

986:2x 17x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 141380238676/(1x2)

LCM = 141380238676/2

LCM = 70690119338

Thus, we can understand that the LCM of 397,838,431,986 is 70690119338.
