Given numbers are 974,234,404,638

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

The LCM of 974,234,404,638 is 7343225604.

Find LCM of 974,234,404,638 with Prime Factorization

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

2 x 487 x 117 x 202 x 319 = 7343225604

Therefore, the lowest common multiple of 974,234,404,638 is 7343225604.

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.

974 x 234 x 404 x 638 = 58745804832

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.

974 : 1, 2, 487, 974

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

404 : 1, 2, 4, 101, 202, 404

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,234,404,638, is 2.

Now, the common factors can be found like this.

974:2x 487

234:2x 3x 3x 13

404:2x 2x 101

638:2x 11x 29

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 = 58745804832/(2x4)

LCM = 58745804832/8

LCM = 7343225604

Thus, we can understand that the LCM of 974,234,404,638 is 7343225604.
