Given numbers are 855,247,949,961

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

The LCM of 855,247,949,961 is 779750595.

Find LCM of 855,247,949,961 with Prime Factorization

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

13 x 19 x 45 x 1 x 73 x 961 = 779750595

Therefore, the lowest common multiple of 855,247,949,961 is 779750595.

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.

855 x 247 x 949 x 961 = 192598396965

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

247 : 1, 13, 19, 247

949 : 1, 13, 73, 949

961 : 1, 31, 961

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,247,949,961, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

247:13x 19

949:13x 73

961:31x 31

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

13x 19 = 247

Therefore, the value for common factors is 247.

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 = 192598396965/(1x247)

LCM = 192598396965/247

LCM = 779750595

Thus, we can understand that the LCM of 855,247,949,961 is 779750595.
