Given numbers are 247,630,728,497

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

The LCM of 247,630,728,497 is 44193240.

Find LCM of 247,630,728,497 with Prime Factorization

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

2 x 7 x 13 x 19 x 45 x 4 x 71 = 44193240

Therefore, the lowest common multiple of 247,630,728,497 is 44193240.

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.

247 x 630 x 728 x 497 = 56302187760

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.

247 : 1, 13, 19, 247

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

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,630,728,497, is 1.

Now, the common factors can be found like this.

247:13x 19

630:2x 3x 3x 5x 7

728:2x 2x 2x 7x 13

497:7x 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 7x 7x 13 = 1274

Therefore, the value for common factors is 1274.

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 = 56302187760/(1x1274)

LCM = 56302187760/1274

LCM = 44193240

Thus, we can understand that the LCM of 247,630,728,497 is 44193240.
