Given numbers are 399,248,107,974

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

The LCM of 399,248,107,974 is 5156289768.

Find LCM of 399,248,107,974 with Prime Factorization

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

2 x 399 x 124 x 107 x 487 = 5156289768

Therefore, the lowest common multiple of 399,248,107,974 is 5156289768.

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.

399 x 248 x 107 x 974 = 10312579536

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

248 : 1, 2, 4, 8, 31, 62, 124, 248

107 : 1, 107

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,248,107,974, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

248:2x 2x 2x 31

107:107

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.

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 = 10312579536/(1x2)

LCM = 10312579536/2

LCM = 5156289768

Thus, we can understand that the LCM of 399,248,107,974 is 5156289768.
