Given numbers are 909,391,277,161

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

The LCM of 909,391,277,161 is 689157441.

Find LCM of 909,391,277,161 with Prime Factorization

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

23 x 909 x 17 x 277 x 7 = 689157441

Therefore, the lowest common multiple of 909,391,277,161 is 689157441.

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.

909 x 391 x 277 x 161 = 15850621143

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.

909 : 1, 3, 9, 101, 303, 909

391 : 1, 17, 23, 391

277 : 1, 277

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,391,277,161, is 1.

Now, the common factors can be found like this.

909:3x 3x 101

391:17x 23

277:277

161:7x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 15850621143/(1x23)

LCM = 15850621143/23

LCM = 689157441

Thus, we can understand that the LCM of 909,391,277,161 is 689157441.
