Find LCM of 281,193,665,988,386 with Prime Factorization
| 2 | 281, 193, 665, 988, 386 |
| 19 | 281, 193, 665, 494, 193 |
| 193 | 281, 193, 35, 26, 193 |
| 281, 1, 35, 26, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 193 x 281 x 1 x 35 x 26 x 1 = 1875377140
Therefore, the lowest common multiple of 281,193,665,988,386 is 1875377140.
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.
281 x 193 x 665 x 988 x 386 = 13754015944760
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.
281 : 1, 281
193 : 1, 193
665 : 1, 5, 7, 19, 35, 95, 133, 665
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
386 : 1, 2, 193, 386
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,193,665,988,386, is 1.
Now, the common factors can be found like this.
281:281
193:193
665:5x 7x 19
988:2x 2x 13x 19
386:2x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19x 193 = 7334
Therefore, the value for common factors is 7334.
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 = 13754015944760/(1x7334)
LCM = 13754015944760/7334
LCM = 1875377140
Thus, we can understand that the LCM of 281,193,665,988,386 is 1875377140.
