Given numbers are 672,793,419,338,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,793,419,338,390 is 14513422560.
Find LCM of 672,793,419,338,390 with Prime Factorization
| 2 | 672, 793, 419, 338, 390 |
| 3 | 336, 793, 419, 169, 195 |
| 13 | 112, 793, 419, 169, 65 |
| 112, 61, 419, 13, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 112 x 61 x 419 x 13 x 5 = 14513422560
Therefore, the lowest common multiple of 672,793,419,338,390 is 14513422560.
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 793 x 419 x 338 x 390 = 29433220951680
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
793 : 1, 13, 61, 793
419 : 1, 419
338 : 1, 2, 13, 26, 169, 338
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,793,419,338,390, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
793:13x 61
419:419
338:2x 13x 13
390:2x 3x 5x 13
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 3x 13x 13 = 2028
Therefore, the value for common factors is 2028.
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 = 29433220951680/(1x2028)
LCM = 29433220951680/2028
LCM = 14513422560
Thus, we can understand that the LCM of 672,793,419,338,390 is 14513422560.
