Given numbers are 681,458,458,31

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

The LCM of 681,458,458,31 is 9668838.

Find LCM of 681,458,458,31 with Prime Factorization

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

2 x 229 x 681 x 1 x 1 x 31 = 9668838

Therefore, the lowest common multiple of 681,458,458,31 is 9668838.

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.

681 x 458 x 458 x 31 = 4428327804

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.

681 : 1, 3, 227, 681

458 : 1, 2, 229, 458

458 : 1, 2, 229, 458

31 : 1, 31

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,458,458,31, is 1.

Now, the common factors can be found like this.

681:3x 227

458:2x 229

458:2x 229

31:31

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

2x 229 = 458

Therefore, the value for common factors is 458.

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 = 4428327804/(1x458)

LCM = 4428327804/458

LCM = 9668838

Thus, we can understand that the LCM of 681,458,458,31 is 9668838.
