Given numbers are 691,681,681,454

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

The LCM of 691,681,681,454 is 941142.

Find LCM of 691,681,681,454 with Prime Factorization

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

3 x 227 x 691 x 1 x 1 x 2 = 941142

Therefore, the lowest common multiple of 691,681,681,454 is 941142.

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.

691 x 681 x 681 x 454 = 145488318354

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.

691 : 1, 691

681 : 1, 3, 227, 681

681 : 1, 3, 227, 681

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,681,681,454, is 1.

Now, the common factors can be found like this.

691:691

681:3x 227

681:3x 227

454:2x 227

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

3x 227x 227 = 154587

Therefore, the value for common factors is 154587.

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 = 145488318354/(1x154587)

LCM = 145488318354/154587

LCM = 941142

Thus, we can understand that the LCM of 691,681,681,454 is 941142.
