Given numbers are 161,391,261,391

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

The LCM of 161,391,261,391 is 714357.

Find LCM of 161,391,261,391 with Prime Factorization

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

17 x 23 x 7 x 1 x 261 x 1 = 714357

Therefore, the lowest common multiple of 161,391,261,391 is 714357.

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.

161 x 391 x 261 x 391 = 6424212501

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.

161 : 1, 7, 23, 161

391 : 1, 17, 23, 391

261 : 1, 3, 9, 29, 87, 261

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,391,261,391, is 1.

Now, the common factors can be found like this.

161:7x 23

391:17x 23

261:3x 3x 29

391:17x 23

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

17x 23x 23 = 8993

Therefore, the value for common factors is 8993.

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 = 6424212501/(1x8993)

LCM = 6424212501/8993

LCM = 714357

Thus, we can understand that the LCM of 161,391,261,391 is 714357.
