LCM Formula to Find Lowest Common Multiple of 619,880,256,640,180

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.

619 x 880 x 256 x 640 x 180 = 16064446464000

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.

619 : 1, 619

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,880,256,640,180, is 1.

Now, the common factors can be found like this.

619:619

880:2x 2x 2x 2x 5x 11

256:2x 2x 2x 2x 2x 2x 2x 2

640:2x 2x 2x 2x 2x 2x 2x 5

180:2x 2x 3x 3x 5

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 2x 2x 2x 2x 2x 2x 2x 2x 2x 5x 5 = 204800

Therefore, the value for common factors is 204800.

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 = 16064446464000/(1x204800)

LCM = 16064446464000/204800

LCM = 78439680

Thus, we can understand that the LCM of 619,880,256,640,180 is 78439680.
