Given numbers are 662,646,668,974

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

The LCM of 662,646,668,974 is 34780509508.

Find LCM of 662,646,668,974 with Prime Factorization

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

2 x 331 x 323 x 334 x 487 = 34780509508

Therefore, the lowest common multiple of 662,646,668,974 is 34780509508.

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.

662 x 646 x 668 x 974 = 278244076064

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.

662 : 1, 2, 331, 662

646 : 1, 2, 17, 19, 34, 38, 323, 646

668 : 1, 2, 4, 167, 334, 668

974 : 1, 2, 487, 974

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,646,668,974, is 2.

Now, the common factors can be found like this.

662:2x 331

646:2x 17x 19

668:2x 2x 167

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 = 278244076064/(2x4)

LCM = 278244076064/8

LCM = 34780509508

Thus, we can understand that the LCM of 662,646,668,974 is 34780509508.
