Given numbers are 679,402,643,442

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

The LCM of 679,402,643,442 is 38788150674.

Find LCM of 679,402,643,442 with Prime Factorization

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

2 x 679 x 201 x 643 x 221 = 38788150674

Therefore, the lowest common multiple of 679,402,643,442 is 38788150674.

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.

679 x 402 x 643 x 442 = 77576301348

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.

679 : 1, 7, 97, 679

402 : 1, 2, 3, 6, 67, 134, 201, 402

643 : 1, 643

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,402,643,442, is 1.

Now, the common factors can be found like this.

679:7x 97

402:2x 3x 67

643:643

442:2x 13x 17

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 = 77576301348/(1x2)

LCM = 77576301348/2

LCM = 38788150674

Thus, we can understand that the LCM of 679,402,643,442 is 38788150674.
