LCM Formula to Find Lowest Common Multiple of 520,249,248,945

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.

520 x 249 x 248 x 945 = 30344932800

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

249 : 1, 3, 83, 249

248 : 1, 2, 4, 8, 31, 62, 124, 248

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,249,248,945, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

249:3x 83

248:2x 2x 2x 31

945:3x 3x 3x 5x 7

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 5 = 120

Therefore, the value for common factors is 120.

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 = 30344932800/(1x120)

LCM = 30344932800/120

LCM = 252874440

Thus, we can understand that the LCM of 520,249,248,945 is 252874440.
