Given numbers are 887,644,315,853
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 887,644,315,853 is 21926586780.
Find LCM of 887,644,315,853 with Prime Factorization
| 7 | 887, 644, 315, 853 |
| 887, 92, 45, 853 |
Multiply the prime numbers at the bottom and the left side.
7 x 887 x 92 x 45 x 853 = 21926586780
Therefore, the lowest common multiple of 887,644,315,853 is 21926586780.
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.
887 x 644 x 315 x 853 = 153486107460
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.
887 : 1, 887
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
853 : 1, 853
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 887,644,315,853, is 1.
Now, the common factors can be found like this.
887:887
644:2x 2x 7x 23
315:3x 3x 5x 7
853:853
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 153486107460/(1x7)
LCM = 153486107460/7
LCM = 21926586780
Thus, we can understand that the LCM of 887,644,315,853 is 21926586780.
