Given numbers are 497,639,643,941

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

The LCM of 497,639,643,941 is 2706446799.

Find LCM of 497,639,643,941 with Prime Factorization

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

71 x 7 x 9 x 643 x 941 = 2706446799

Therefore, the lowest common multiple of 497,639,643,941 is 2706446799.

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.

497 x 639 x 643 x 941 = 192157722729

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.

497 : 1, 7, 71, 497

639 : 1, 3, 9, 71, 213, 639

643 : 1, 643

941 : 1, 941

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,639,643,941, is 1.

Now, the common factors can be found like this.

497:7x 71

639:3x 3x 71

643:643

941:941

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

71 = 71

Therefore, the value for common factors is 71.

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 = 192157722729/(1x71)

LCM = 192157722729/71

LCM = 2706446799

Thus, we can understand that the LCM of 497,639,643,941 is 2706446799.
