Given numbers are 247,114,817,643

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

The LCM of 247,114,817,643 is 40975818.

Find LCM of 247,114,817,643 with Prime Factorization

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

19 x 13 x 6 x 43 x 643 = 40975818

Therefore, the lowest common multiple of 247,114,817,643 is 40975818.

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 114 x 817 x 643 = 14792270298

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

114 : 1, 2, 3, 6, 19, 38, 57, 114

817 : 1, 19, 43, 817

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,114,817,643, is 1.

Now, the common factors can be found like this.

247:13x 19

114:2x 3x 19

817:19x 43

643:643

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

19x 19 = 361

Therefore, the value for common factors is 361.

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 = 14792270298/(1x361)

LCM = 14792270298/361

LCM = 40975818

Thus, we can understand that the LCM of 247,114,817,643 is 40975818.
