LCM Formula to Find Lowest Common Multiple of 978,928,374,480

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.

978 x 928 x 374 x 480 = 162929479680

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.

978 : 1, 2, 3, 6, 163, 326, 489, 978

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

374 : 1, 2, 11, 17, 22, 34, 187, 374

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,928,374,480, is 2.

Now, the common factors can be found like this.

978:2x 3x 163

928:2x 2x 2x 2x 2x 29

374:2x 11x 17

480:2x 2x 2x 2x 2x 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 3 = 192

Therefore, the value for common factors is 192.

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 = 162929479680/(2x192)

LCM = 162929479680/384

LCM = 424295520

Thus, we can understand that the LCM of 978,928,374,480 is 424295520.
