Given numbers are 724,341,838,21

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

The LCM of 724,341,838,21 is 2172332316.

Find LCM of 724,341,838,21 with Prime Factorization

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

2 x 362 x 341 x 419 x 21 = 2172332316

Therefore, the lowest common multiple of 724,341,838,21 is 2172332316.

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.

724 x 341 x 838 x 21 = 4344664632

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.

724 : 1, 2, 4, 181, 362, 724

341 : 1, 11, 31, 341

838 : 1, 2, 419, 838

21 : 1, 3, 7, 21

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,341,838,21, is 1.

Now, the common factors can be found like this.

724:2x 2x 181

341:11x 31

838:2x 419

21:3x 7

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 = 4344664632/(1x2)

LCM = 4344664632/2

LCM = 2172332316

Thus, we can understand that the LCM of 724,341,838,21 is 2172332316.
