Given numbers are 253,639,165,863
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,639,165,863 is 697593105.
Find LCM of 253,639,165,863 with Prime Factorization
| 3 | 253, 639, 165, 863 |
| 11 | 253, 213, 55, 863 |
| 23, 213, 5, 863 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 23 x 213 x 5 x 863 = 697593105
Therefore, the lowest common multiple of 253,639,165,863 is 697593105.
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.
253 x 639 x 165 x 863 = 23020572465
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.
253 : 1, 11, 23, 253
639 : 1, 3, 9, 71, 213, 639
165 : 1, 3, 5, 11, 15, 33, 55, 165
863 : 1, 863
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,639,165,863, is 1.
Now, the common factors can be found like this.
253:11x 23
639:3x 3x 71
165:3x 5x 11
863:863
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 23020572465/(1x33)
LCM = 23020572465/33
LCM = 697593105
Thus, we can understand that the LCM of 253,639,165,863 is 697593105.
