Given numbers are 930,819,949,445
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 930,819,949,445 is 1649523330.
Find LCM of 930,819,949,445 with Prime Factorization
| 3 | 930, 819, 949, 445 |
| 5 | 310, 273, 949, 445 |
| 13 | 62, 273, 949, 89 |
| 62, 21, 73, 89 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 62 x 21 x 73 x 89 = 1649523330
Therefore, the lowest common multiple of 930,819,949,445 is 1649523330.
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.
930 x 819 x 949 x 445 = 321657049350
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.
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
949 : 1, 13, 73, 949
445 : 1, 5, 89, 445
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 930,819,949,445, is 1.
Now, the common factors can be found like this.
930:2x 3x 5x 31
819:3x 3x 7x 13
949:13x 73
445:5x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13 = 195
Therefore, the value for common factors is 195.
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 = 321657049350/(1x195)
LCM = 321657049350/195
LCM = 1649523330
Thus, we can understand that the LCM of 930,819,949,445 is 1649523330.
