Given numbers are 279,912,284,470,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,912,284,470,923 is 18397014480.
Find LCM of 279,912,284,470,923 with Prime Factorization
| 2 | 279, 912, 284, 470, 923 |
| 2 | 279, 456, 142, 235, 923 |
| 3 | 279, 228, 71, 235, 923 |
| 71 | 93, 76, 71, 235, 923 |
| 93, 76, 1, 235, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 71 x 93 x 76 x 1 x 235 x 13 = 18397014480
Therefore, the lowest common multiple of 279,912,284,470,923 is 18397014480.
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.
279 x 912 x 284 x 470 x 923 = 31348512673920
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.
279 : 1, 3, 9, 31, 93, 279
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
284 : 1, 2, 4, 71, 142, 284
470 : 1, 2, 5, 10, 47, 94, 235, 470
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,912,284,470,923, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
912:2x 2x 2x 2x 3x 19
284:2x 2x 71
470:2x 5x 47
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 2x 2x 3x 71 = 1704
Therefore, the value for common factors is 1704.
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 = 31348512673920/(1x1704)
LCM = 31348512673920/1704
LCM = 18397014480
Thus, we can understand that the LCM of 279,912,284,470,923 is 18397014480.
