Given numbers are 620,341,638,353

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

The LCM of 620,341,638,353 is 69816340.

Find LCM of 620,341,638,353 with Prime Factorization

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

2 x 11 x 31 x 10 x 1 x 29 x 353 = 69816340

Therefore, the lowest common multiple of 620,341,638,353 is 69816340.

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.

620 x 341 x 638 x 353 = 47614743880

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.

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

341 : 1, 11, 31, 341

638 : 1, 2, 11, 22, 29, 58, 319, 638

353 : 1, 353

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,341,638,353, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

341:11x 31

638:2x 11x 29

353:353

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

2x 11x 31 = 682

Therefore, the value for common factors is 682.

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 = 47614743880/(1x682)

LCM = 47614743880/682

LCM = 69816340

Thus, we can understand that the LCM of 620,341,638,353 is 69816340.
