LCM Formula to Find Lowest Common Multiple of 630,261,990,670,142

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.

630 x 261 x 990 x 670 x 142 = 15487431498000

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.

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

261 : 1, 3, 9, 29, 87, 261

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

670 : 1, 2, 5, 10, 67, 134, 335, 670

142 : 1, 2, 71, 142

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,261,990,670,142, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

261:3x 3x 29

990:2x 3x 3x 5x 11

670:2x 5x 67

142:2x 71

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 3x 3x 3x 5x 5 = 16200

Therefore, the value for common factors is 16200.

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 = 15487431498000/(1x16200)

LCM = 15487431498000/16200

LCM = 956014290

Thus, we can understand that the LCM of 630,261,990,670,142 is 956014290.
