LCM Formula to Find Lowest Common Multiple of 855,945,721,246,910

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 945 x 721 x 246 x 910 = 130409637403500

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

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

721 : 1, 7, 103, 721

246 : 1, 2, 3, 6, 41, 82, 123, 246

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,945,721,246,910, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

945:3x 3x 3x 5x 7

721:7x 103

246:2x 3x 41

910:2x 5x 7x 13

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

2x 3x 3x 3x 5x 5x 7x 7 = 66150

Therefore, the value for common factors is 66150.

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 = 130409637403500/(1x66150)

LCM = 130409637403500/66150

LCM = 1971423090

Thus, we can understand that the LCM of 855,945,721,246,910 is 1971423090.
