Given numbers are 191,238,902,289,357
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,238,902,289,357 is 1045579458.
Find LCM of 191,238,902,289,357 with Prime Factorization
| 2 | 191, 238, 902, 289, 357 |
| 7 | 191, 119, 451, 289, 357 |
| 17 | 191, 17, 451, 289, 51 |
| 191, 1, 451, 17, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 191 x 1 x 451 x 17 x 3 = 1045579458
Therefore, the lowest common multiple of 191,238,902,289,357 is 1045579458.
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.
191 x 238 x 902 x 289 x 357 = 4230414487068
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.
191 : 1, 191
238 : 1, 2, 7, 14, 17, 34, 119, 238
902 : 1, 2, 11, 22, 41, 82, 451, 902
289 : 1, 17, 289
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,238,902,289,357, is 1.
Now, the common factors can be found like this.
191:191
238:2x 7x 17
902:2x 11x 41
289:17x 17
357:3x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 17x 17 = 4046
Therefore, the value for common factors is 4046.
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 = 4230414487068/(1x4046)
LCM = 4230414487068/4046
LCM = 1045579458
Thus, we can understand that the LCM of 191,238,902,289,357 is 1045579458.
