Given numbers are 869,515,374,869,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,515,374,869,945 is 2875859910.
Find LCM of 869,515,374,869,945 with Prime Factorization
| 5 | 869, 515, 374, 869, 945 |
| 11 | 869, 103, 374, 869, 189 |
| 79 | 79, 103, 34, 79, 189 |
| 1, 103, 34, 1, 189 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 79 x 1 x 103 x 34 x 1 x 189 = 2875859910
Therefore, the lowest common multiple of 869,515,374,869,945 is 2875859910.
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.
869 x 515 x 374 x 869 x 945 = 137451724398450
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.
869 : 1, 11, 79, 869
515 : 1, 5, 103, 515
374 : 1, 2, 11, 17, 22, 34, 187, 374
869 : 1, 11, 79, 869
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,515,374,869,945, is 1.
Now, the common factors can be found like this.
869:11x 79
515:5x 103
374:2x 11x 17
869:11x 79
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 11x 79 = 47795
Therefore, the value for common factors is 47795.
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 = 137451724398450/(1x47795)
LCM = 137451724398450/47795
LCM = 2875859910
Thus, we can understand that the LCM of 869,515,374,869,945 is 2875859910.
