Given numbers are 2921,5428

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

The LCM of 2921,5428 is 689356.

Find LCM of 2921,5428 with Prime Factorization

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

23 x 127 x 236 = 689356

Therefore, the lowest common multiple of 2921,5428 is 689356.

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.

2921 x 5428 = 15855188

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.

2921 : 1, 23, 127, 2921

5428 : 1, 2, 4, 23, 46, 59, 92, 118, 236, 1357, 2714, 5428

23 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2921,5428, is 23.

Now, the common factors can be found like this.

2921:23x 127

5428:2x 2x 23x 59

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

= 1

Therefore, the value for common factors is 1.

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 = 15855188/(23x1)

LCM = 15855188/23

LCM = 689356

Thus, we can understand that the LCM of 2921,5428 is 689356.
