Given numbers are 668,506,406,973

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

The LCM of 668,506,406,973 is 4768785868.

Find LCM of 668,506,406,973 with Prime Factorization

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

2 x 7 x 334 x 253 x 29 x 139 = 4768785868

Therefore, the lowest common multiple of 668,506,406,973 is 4768785868.

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.

668 x 506 x 406 x 973 = 133526004304

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.

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

506 : 1, 2, 11, 22, 23, 46, 253, 506

406 : 1, 2, 7, 14, 29, 58, 203, 406

973 : 1, 7, 139, 973

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,506,406,973, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

506:2x 11x 23

406:2x 7x 29

973:7x 139

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

2x 2x 7 = 28

Therefore, the value for common factors is 28.

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 = 133526004304/(1x28)

LCM = 133526004304/28

LCM = 4768785868

Thus, we can understand that the LCM of 668,506,406,973 is 4768785868.
