Given numbers are 872,649,140,143,971
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 872,649,140,143,971 is 250029820040.
Find LCM of 872,649,140,143,971 with Prime Factorization
| 2 | 872, 649, 140, 143, 971 |
| 2 | 436, 649, 70, 143, 971 |
| 11 | 218, 649, 35, 143, 971 |
| 218, 59, 35, 13, 971 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 218 x 59 x 35 x 13 x 971 = 250029820040
Therefore, the lowest common multiple of 872,649,140,143,971 is 250029820040.
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.
872 x 649 x 140 x 143 x 971 = 11001312081760
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.
872 : 1, 2, 4, 8, 109, 218, 436, 872
649 : 1, 11, 59, 649
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
143 : 1, 11, 13, 143
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,649,140,143,971, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
649:11x 59
140:2x 2x 5x 7
143:11x 13
971:971
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11 = 44
Therefore, the value for common factors is 44.
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 = 11001312081760/(1x44)
LCM = 11001312081760/44
LCM = 250029820040
Thus, we can understand that the LCM of 872,649,140,143,971 is 250029820040.
