Given numbers are 672,580,389,944
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,580,389,944 is 2236345440.
Find LCM of 672,580,389,944 with Prime Factorization
| 2 | 672, 580, 389, 944 |
| 2 | 336, 290, 389, 472 |
| 2 | 168, 145, 389, 236 |
| 2 | 84, 145, 389, 118 |
| 42, 145, 389, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 42 x 145 x 389 x 59 = 2236345440
Therefore, the lowest common multiple of 672,580,389,944 is 2236345440.
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.
672 x 580 x 389 x 944 = 143126108160
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.
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
389 : 1, 389
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,580,389,944, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
580:2x 2x 5x 29
389:389
944:2x 2x 2x 2x 59
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 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 143126108160/(1x64)
LCM = 143126108160/64
LCM = 2236345440
Thus, we can understand that the LCM of 672,580,389,944 is 2236345440.
