Given numbers are 905,214,856,609

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

The LCM of 905,214,856,609 is 471780120.

Find LCM of 905,214,856,609 with Prime Factorization

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

2 x 107 x 905 x 1 x 4 x 609 = 471780120

Therefore, the lowest common multiple of 905,214,856,609 is 471780120.

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.

905 x 214 x 856 x 609 = 100960945680

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.

905 : 1, 5, 181, 905

214 : 1, 2, 107, 214

856 : 1, 2, 4, 8, 107, 214, 428, 856

609 : 1, 3, 7, 21, 29, 87, 203, 609

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,214,856,609, is 1.

Now, the common factors can be found like this.

905:5x 181

214:2x 107

856:2x 2x 2x 107

609:3x 7x 29

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

2x 107 = 214

Therefore, the value for common factors is 214.

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 = 100960945680/(1x214)

LCM = 100960945680/214

LCM = 471780120

Thus, we can understand that the LCM of 905,214,856,609 is 471780120.
