LCM Formula to Find Lowest Common Multiple of 961,768,225,560

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.

961 x 768 x 225 x 560 = 92994048000

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.

961 : 1, 31, 961

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,768,225,560, is 1.

Now, the common factors can be found like this.

961:31x 31

768:2x 2x 2x 2x 2x 2x 2x 2x 3

225:3x 3x 5x 5

560:2x 2x 2x 2x 5x 7

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 2x 3x 5 = 240

Therefore, the value for common factors is 240.

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 = 92994048000/(1x240)

LCM = 92994048000/240

LCM = 387475200

Thus, we can understand that the LCM of 961,768,225,560 is 387475200.
