LCM Formula to Find Lowest Common Multiple of 440,891,678,620

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.

440 x 891 x 678 x 620 = 164797934400

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.

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

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

678 : 1, 2, 3, 6, 113, 226, 339, 678

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,891,678,620, is 1.

Now, the common factors can be found like this.

440:2x 2x 2x 5x 11

891:3x 3x 3x 3x 11

678:2x 3x 113

620:2x 2x 5x 31

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 5x 11 = 1320

Therefore, the value for common factors is 1320.

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 = 164797934400/(1x1320)

LCM = 164797934400/1320

LCM = 124846920

Thus, we can understand that the LCM of 440,891,678,620 is 124846920.
