Find LCM of 140,618,117,143,665 with Prime Factorization
| 2 | 140, 618, 117, 143, 665 |
| 3 | 70, 309, 117, 143, 665 |
| 5 | 70, 103, 39, 143, 665 |
| 7 | 14, 103, 39, 143, 133 |
| 13 | 2, 103, 39, 143, 19 |
| 2, 103, 3, 11, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 13 x 2 x 103 x 3 x 11 x 19 = 352612260
Therefore, the lowest common multiple of 140,618,117,143,665 is 352612260.
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.
140 x 618 x 117 x 143 x 665 = 962631469800
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
618 : 1, 2, 3, 6, 103, 206, 309, 618
117 : 1, 3, 9, 13, 39, 117
143 : 1, 11, 13, 143
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,618,117,143,665, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
618:2x 3x 103
117:3x 3x 13
143:11x 13
665:5x 7x 19
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 5x 7x 13 = 2730
Therefore, the value for common factors is 2730.
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 = 962631469800/(1x2730)
LCM = 962631469800/2730
LCM = 352612260
Thus, we can understand that the LCM of 140,618,117,143,665 is 352612260.
