Given numbers are 771,221,826,878

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

The LCM of 771,221,826,878 is 61786162074.

Find LCM of 771,221,826,878 with Prime Factorization

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

2 x 771 x 221 x 413 x 439 = 61786162074

Therefore, the lowest common multiple of 771,221,826,878 is 61786162074.

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.

771 x 221 x 826 x 878 = 123572324148

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.

771 : 1, 3, 257, 771

221 : 1, 13, 17, 221

826 : 1, 2, 7, 14, 59, 118, 413, 826

878 : 1, 2, 439, 878

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,221,826,878, is 1.

Now, the common factors can be found like this.

771:3x 257

221:13x 17

826:2x 7x 59

878:2x 439

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 = 123572324148/(1x2)

LCM = 123572324148/2

LCM = 61786162074

Thus, we can understand that the LCM of 771,221,826,878 is 61786162074.
