Given numbers are 430,949,989,438,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 430,949,989,438,923 is 1999134930.
Find LCM of 430,949,989,438,923 with Prime Factorization
| 2 | 430, 949, 989, 438, 923 |
| 13 | 215, 949, 989, 219, 923 |
| 43 | 215, 73, 989, 219, 71 |
| 73 | 5, 73, 23, 219, 71 |
| 5, 1, 23, 3, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 43 x 73 x 5 x 1 x 23 x 3 x 71 = 1999134930
Therefore, the lowest common multiple of 430,949,989,438,923 is 1999134930.
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.
430 x 949 x 989 x 438 x 923 = 163157398177020
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.
430 : 1, 2, 5, 10, 43, 86, 215, 430
949 : 1, 13, 73, 949
989 : 1, 23, 43, 989
438 : 1, 2, 3, 6, 73, 146, 219, 438
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,949,989,438,923, is 1.
Now, the common factors can be found like this.
430:2x 5x 43
949:13x 73
989:23x 43
438:2x 3x 73
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 43x 73 = 81614
Therefore, the value for common factors is 81614.
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 = 163157398177020/(1x81614)
LCM = 163157398177020/81614
LCM = 1999134930
Thus, we can understand that the LCM of 430,949,989,438,923 is 1999134930.
