Given numbers are 874,638,721,394,169

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

The LCM of 874,638,721,394,169 is 6692529761918.

Find LCM of 874,638,721,394,169 with Prime Factorization

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

2 x 437 x 319 x 721 x 197 x 169 = 6692529761918

Therefore, the lowest common multiple of 874,638,721,394,169 is 6692529761918.

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.

874 x 638 x 721 x 394 x 169 = 26770119047672

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.

874 : 1, 2, 19, 23, 38, 46, 437, 874

638 : 1, 2, 11, 22, 29, 58, 319, 638

721 : 1, 7, 103, 721

394 : 1, 2, 197, 394

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,638,721,394,169, is 1.

Now, the common factors can be found like this.

874:2x 19x 23

638:2x 11x 29

721:7x 103

394:2x 197

169:13x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 26770119047672/(1x4)

LCM = 26770119047672/4

LCM = 6692529761918

Thus, we can understand that the LCM of 874,638,721,394,169 is 6692529761918.
