Given numbers are 398,724,854,974

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

The LCM of 398,724,854,974 is 29960460124.

Find LCM of 398,724,854,974 with Prime Factorization

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

2 x 199 x 362 x 427 x 487 = 29960460124

Therefore, the lowest common multiple of 398,724,854,974 is 29960460124.

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.

398 x 724 x 854 x 974 = 239683680992

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.

398 : 1, 2, 199, 398

724 : 1, 2, 4, 181, 362, 724

854 : 1, 2, 7, 14, 61, 122, 427, 854

974 : 1, 2, 487, 974

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,724,854,974, is 2.

Now, the common factors can be found like this.

398:2x 199

724:2x 2x 181

854:2x 7x 61

974:2x 487

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 = 239683680992/(2x4)

LCM = 239683680992/8

LCM = 29960460124

Thus, we can understand that the LCM of 398,724,854,974 is 29960460124.
