Given numbers are 630,717,420,182

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 630,717,420,182 is 3914820.

Find LCM of 630,717,420,182 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 5 x 7 x 3 x 239 x 2 x 13 = 3914820

Therefore, the lowest common multiple of 630,717,420,182 is 3914820.

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 717 x 420 x 182 = 34528712400

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

717 : 1, 3, 239, 717

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

182 : 1, 2, 7, 13, 14, 26, 91, 182

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,717,420,182, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

717:3x 239

420:2x 2x 3x 5x 7

182:2x 7x 13

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 3x 3x 5x 7x 7 = 8820

Therefore, the value for common factors is 8820.

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 = 34528712400/(1x8820)

LCM = 34528712400/8820

LCM = 3914820

Thus, we can understand that the LCM of 630,717,420,182 is 3914820.
