Given numbers are 557,248,427,770

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

The LCM of 557,248,427,770 is 3244123960.

Find LCM of 557,248,427,770 with Prime Factorization

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

2 x 7 x 557 x 124 x 61 x 55 = 3244123960

Therefore, the lowest common multiple of 557,248,427,770 is 3244123960.

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 248 x 427 x 770 = 45417735440

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

248 : 1, 2, 4, 8, 31, 62, 124, 248

427 : 1, 7, 61, 427

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 557,248,427,770, is 1.

Now, the common factors can be found like this.

557:557

248:2x 2x 2x 31

427:7x 61

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 7 = 14

Therefore, the value for common factors is 14.

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 = 45417735440/(1x14)

LCM = 45417735440/14

LCM = 3244123960

Thus, we can understand that the LCM of 557,248,427,770 is 3244123960.
