Given numbers are 557,770,586,421

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

The LCM of 557,770,586,421 is 52904868170.

Find LCM of 557,770,586,421 with Prime Factorization

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

2 x 557 x 385 x 293 x 421 = 52904868170

Therefore, the lowest common multiple of 557,770,586,421 is 52904868170.

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.

557 x 770 x 586 x 421 = 105809736340

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.

557 : 1, 557

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

586 : 1, 2, 293, 586

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,770,586,421, is 1.

Now, the common factors can be found like this.

557:557

770:2x 5x 7x 11

586:2x 293

421:421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 105809736340/(1x2)

LCM = 105809736340/2

LCM = 52904868170

Thus, we can understand that the LCM of 557,770,586,421 is 52904868170.
