Given numbers are 291,398,406,770

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

The LCM of 291,398,406,770 is 1293107970.

Find LCM of 291,398,406,770 with Prime Factorization

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

2 x 7 x 291 x 199 x 29 x 55 = 1293107970

Therefore, the lowest common multiple of 291,398,406,770 is 1293107970.

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.

291 x 398 x 406 x 770 = 36207023160

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.

291 : 1, 3, 97, 291

398 : 1, 2, 199, 398

406 : 1, 2, 7, 14, 29, 58, 203, 406

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,398,406,770, is 1.

Now, the common factors can be found like this.

291:3x 97

398:2x 199

406:2x 7x 29

770:2x 5x 7x 11

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

2x 2x 7 = 28

Therefore, the value for common factors is 28.

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 = 36207023160/(1x28)

LCM = 36207023160/28

LCM = 1293107970

Thus, we can understand that the LCM of 291,398,406,770 is 1293107970.
