Find LCM of 918,997,210,345,742 with Prime Factorization
| 2 | 918, 997, 210, 345, 742 |
| 3 | 459, 997, 105, 345, 371 |
| 5 | 153, 997, 35, 115, 371 |
| 7 | 153, 997, 7, 23, 371 |
| 153, 997, 1, 23, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 153 x 997 x 1 x 23 x 53 = 39048970590
Therefore, the lowest common multiple of 918,997,210,345,742 is 39048970590.
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.
918 x 997 x 210 x 345 x 742 = 49201702943400
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
997 : 1, 997
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
345 : 1, 3, 5, 15, 23, 69, 115, 345
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,997,210,345,742, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
997:997
210:2x 3x 5x 7
345:3x 5x 23
742:2x 7x 53
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 3x 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 49201702943400/(1x1260)
LCM = 49201702943400/1260
LCM = 39048970590
Thus, we can understand that the LCM of 918,997,210,345,742 is 39048970590.
