Given numbers are 397,157,581,581

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

The LCM of 397,157,581,581 is 36213149.

Find LCM of 397,157,581,581 with Prime Factorization

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

7 x 83 x 397 x 157 x 1 x 1 = 36213149

Therefore, the lowest common multiple of 397,157,581,581 is 36213149.

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.

397 x 157 x 581 x 581 = 21039839569

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.

397 : 1, 397

157 : 1, 157

581 : 1, 7, 83, 581

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,157,581,581, is 1.

Now, the common factors can be found like this.

397:397

157:157

581:7x 83

581:7x 83

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

7x 83 = 581

Therefore, the value for common factors is 581.

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 = 21039839569/(1x581)

LCM = 21039839569/581

LCM = 36213149

Thus, we can understand that the LCM of 397,157,581,581 is 36213149.
