Given numbers are 357,749,261,427
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 357,749,261,427 is 202722093.
Find LCM of 357,749,261,427 with Prime Factorization
| 3 | 357, 749, 261, 427 |
| 7 | 119, 749, 87, 427 |
| 17, 107, 87, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 17 x 107 x 87 x 61 = 202722093
Therefore, the lowest common multiple of 357,749,261,427 is 202722093.
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.
357 x 749 x 261 x 427 = 29800147671
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
749 : 1, 7, 107, 749
261 : 1, 3, 9, 29, 87, 261
427 : 1, 7, 61, 427
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,749,261,427, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
749:7x 107
261:3x 3x 29
427:7x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 29800147671/(1x147)
LCM = 29800147671/147
LCM = 202722093
Thus, we can understand that the LCM of 357,749,261,427 is 202722093.
