Given numbers are 945,321,217,341
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 945,321,217,341 is 34480215.
Find LCM of 945,321,217,341 with Prime Factorization
| 3 | 945, 321, 217, 341 |
| 7 | 315, 107, 217, 341 |
| 31 | 45, 107, 31, 341 |
| 45, 107, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 31 x 45 x 107 x 1 x 11 = 34480215
Therefore, the lowest common multiple of 945,321,217,341 is 34480215.
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.
945 x 321 x 217 x 341 = 22446619965
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
321 : 1, 3, 107, 321
217 : 1, 7, 31, 217
341 : 1, 11, 31, 341
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,321,217,341, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
321:3x 107
217:7x 31
341:11x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 31 = 651
Therefore, the value for common factors is 651.
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 = 22446619965/(1x651)
LCM = 22446619965/651
LCM = 34480215
Thus, we can understand that the LCM of 945,321,217,341 is 34480215.
