LCM Formula to Find Lowest Common Multiple of 821,960,686,646

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.

821 x 960 x 686 x 646 = 349277832960

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.

821 : 1, 821

960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960

686 : 1, 2, 7, 14, 49, 98, 343, 686

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,960,686,646, is 1.

Now, the common factors can be found like this.

821:821

960:2x 2x 2x 2x 2x 2x 3x 5

686:2x 7x 7x 7

646:2x 17x 19

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 349277832960/(1x4)

LCM = 349277832960/4

LCM = 87319458240

Thus, we can understand that the LCM of 821,960,686,646 is 87319458240.
