LCM Formula to Find Lowest Common Multiple of 920,448,867,380,978

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.

920 x 448 x 867 x 380 x 978 = 132802848460800

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

867 : 1, 3, 17, 51, 289, 867

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,448,867,380,978, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

448:2x 2x 2x 2x 2x 2x 7

867:3x 17x 17

380:2x 2x 5x 19

978:2x 3x 163

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 3x 5 = 960

Therefore, the value for common factors is 960.

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 = 132802848460800/(1x960)

LCM = 132802848460800/960

LCM = 138336300480

Thus, we can understand that the LCM of 920,448,867,380,978 is 138336300480.
