Given numbers are 641,161,518,529

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

The LCM of 641,161,518,529 is 175648102.

Find LCM of 641,161,518,529 with Prime Factorization

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

7 x 23 x 641 x 1 x 74 x 23 = 175648102

Therefore, the lowest common multiple of 641,161,518,529 is 175648102.

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.

641 x 161 x 518 x 529 = 28279344422

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.

641 : 1, 641

161 : 1, 7, 23, 161

518 : 1, 2, 7, 14, 37, 74, 259, 518

529 : 1, 23, 529

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,161,518,529, is 1.

Now, the common factors can be found like this.

641:641

161:7x 23

518:2x 7x 37

529:23x 23

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 28279344422/(1x161)

LCM = 28279344422/161

LCM = 175648102

Thus, we can understand that the LCM of 641,161,518,529 is 175648102.
