Given numbers are 701,620,398,217

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

The LCM of 701,620,398,217 is 605425660.

Find LCM of 701,620,398,217 with Prime Factorization

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

2 x 31 x 701 x 10 x 199 x 7 = 605425660

Therefore, the lowest common multiple of 701,620,398,217 is 605425660.

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.

701 x 620 x 398 x 217 = 37536390920

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.

701 : 1, 701

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

398 : 1, 2, 199, 398

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 701,620,398,217, is 1.

Now, the common factors can be found like this.

701:701

620:2x 2x 5x 31

398:2x 199

217:7x 31

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

2x 31 = 62

Therefore, the value for common factors is 62.

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 = 37536390920/(1x62)

LCM = 37536390920/62

LCM = 605425660

Thus, we can understand that the LCM of 701,620,398,217 is 605425660.
