Find LCM of 665,286,126,770,353 with Prime Factorization
| 2 | 665, 286, 126, 770, 353 |
| 5 | 665, 143, 63, 385, 353 |
| 7 | 133, 143, 63, 77, 353 |
| 11 | 19, 143, 9, 11, 353 |
| 19, 13, 9, 1, 353 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 19 x 13 x 9 x 1 x 353 = 604233630
Therefore, the lowest common multiple of 665,286,126,770,353 is 604233630.
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.
665 x 286 x 126 x 770 x 353 = 6513638531400
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
286 : 1, 2, 11, 13, 22, 26, 143, 286
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
353 : 1, 353
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,286,126,770,353, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
286:2x 11x 13
126:2x 3x 3x 7
770:2x 5x 7x 11
353:353
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 5x 7x 7x 11 = 10780
Therefore, the value for common factors is 10780.
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 = 6513638531400/(1x10780)
LCM = 6513638531400/10780
LCM = 604233630
Thus, we can understand that the LCM of 665,286,126,770,353 is 604233630.
