LCM Formula to Find Lowest Common Multiple of 945,200,921,432,153

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.

945 x 200 x 921 x 432 x 153 = 11505264624000

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.

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

200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200

921 : 1, 3, 307, 921

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

153 : 1, 3, 9, 17, 51, 153

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,200,921,432,153, is 1.

Now, the common factors can be found like this.

945:3x 3x 3x 5x 7

200:2x 2x 2x 5x 5

921:3x 307

432:2x 2x 2x 2x 3x 3x 3

153:3x 3x 17

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

2x 2x 2x 3x 3x 3x 3x 3x 3x 5 = 29160

Therefore, the value for common factors is 29160.

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 = 11505264624000/(1x29160)

LCM = 11505264624000/29160

LCM = 394556400

Thus, we can understand that the LCM of 945,200,921,432,153 is 394556400.
