Given numbers are 630,209,743,286

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

The LCM of 630,209,743,286 is 1271800530.

Find LCM of 630,209,743,286 with Prime Factorization

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

2 x 11 x 315 x 19 x 743 x 13 = 1271800530

Therefore, the lowest common multiple of 630,209,743,286 is 1271800530.

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 209 x 743 x 286 = 27979611660

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

209 : 1, 11, 19, 209

743 : 1, 743

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,209,743,286, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

209:11x 19

743:743

286:2x 11x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 27979611660/(1x22)

LCM = 27979611660/22

LCM = 1271800530

Thus, we can understand that the LCM of 630,209,743,286 is 1271800530.
