Given numbers are 391,603,705,469

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

The LCM of 391,603,705,469 is 387846585.

Find LCM of 391,603,705,469 with Prime Factorization

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

3 x 67 x 391 x 3 x 235 x 7 = 387846585

Therefore, the lowest common multiple of 391,603,705,469 is 387846585.

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.

391 x 603 x 705 x 469 = 77957163585

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.

391 : 1, 17, 23, 391

603 : 1, 3, 9, 67, 201, 603

705 : 1, 3, 5, 15, 47, 141, 235, 705

469 : 1, 7, 67, 469

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,603,705,469, is 1.

Now, the common factors can be found like this.

391:17x 23

603:3x 3x 67

705:3x 5x 47

469:7x 67

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

3x 67 = 201

Therefore, the value for common factors is 201.

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 = 77957163585/(1x201)

LCM = 77957163585/201

LCM = 387846585

Thus, we can understand that the LCM of 391,603,705,469 is 387846585.
