Given numbers are 721,454,357,672,149
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,454,357,672,149 is 39798577056.
Find LCM of 721,454,357,672,149 with Prime Factorization
| 2 | 721, 454, 357, 672, 149 |
| 3 | 721, 227, 357, 336, 149 |
| 7 | 721, 227, 119, 112, 149 |
| 103, 227, 17, 16, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 103 x 227 x 17 x 16 x 149 = 39798577056
Therefore, the lowest common multiple of 721,454,357,672,149 is 39798577056.
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.
721 x 454 x 357 x 672 x 149 = 11700781654464
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.
721 : 1, 7, 103, 721
454 : 1, 2, 227, 454
357 : 1, 3, 7, 17, 21, 51, 119, 357
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
149 : 1, 149
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,454,357,672,149, is 1.
Now, the common factors can be found like this.
721:7x 103
454:2x 227
357:3x 7x 17
672:2x 2x 2x 2x 2x 3x 7
149:149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 7 = 294
Therefore, the value for common factors is 294.
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 = 11700781654464/(1x294)
LCM = 11700781654464/294
LCM = 39798577056
Thus, we can understand that the LCM of 721,454,357,672,149 is 39798577056.
