Given numbers are 448,869,170,391

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

The LCM of 448,869,170,391 is 761104960.

Find LCM of 448,869,170,391 with Prime Factorization

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

2 x 17 x 224 x 869 x 5 x 23 = 761104960

Therefore, the lowest common multiple of 448,869,170,391 is 761104960.

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.

448 x 869 x 170 x 391 = 25877568640

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.

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

869 : 1, 11, 79, 869

170 : 1, 2, 5, 10, 17, 34, 85, 170

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 448,869,170,391, is 1.

Now, the common factors can be found like this.

448:2x 2x 2x 2x 2x 2x 7

869:11x 79

170:2x 5x 17

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.

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 25877568640/(1x34)

LCM = 25877568640/34

LCM = 761104960

Thus, we can understand that the LCM of 448,869,170,391 is 761104960.
