Given numbers are 169,957,209,638

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

The LCM of 169,957,209,638 is 6145854.

Find LCM of 169,957,209,638 with Prime Factorization

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

11 x 29 x 169 x 3 x 19 x 2 = 6145854

Therefore, the lowest common multiple of 169,957,209,638 is 6145854.

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.

169 x 957 x 209 x 638 = 21565801686

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.

169 : 1, 13, 169

957 : 1, 3, 11, 29, 33, 87, 319, 957

209 : 1, 11, 19, 209

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,957,209,638, is 1.

Now, the common factors can be found like this.

169:13x 13

957:3x 11x 29

209:11x 19

638:2x 11x 29

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

11x 11x 29 = 3509

Therefore, the value for common factors is 3509.

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 = 21565801686/(1x3509)

LCM = 21565801686/3509

LCM = 6145854

Thus, we can understand that the LCM of 169,957,209,638 is 6145854.
