Find LCM of 517,987,165,508,670 with Prime Factorization
| 2 | 517, 987, 165, 508, 670 |
| 3 | 517, 987, 165, 254, 335 |
| 5 | 517, 329, 55, 254, 335 |
| 11 | 517, 329, 11, 254, 67 |
| 47 | 47, 329, 1, 254, 67 |
| 1, 7, 1, 254, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 47 x 1 x 7 x 1 x 254 x 67 = 1847644260
Therefore, the lowest common multiple of 517,987,165,508,670 is 1847644260.
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.
517 x 987 x 165 x 508 x 670 = 28656962472600
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.
517 : 1, 11, 47, 517
987 : 1, 3, 7, 21, 47, 141, 329, 987
165 : 1, 3, 5, 11, 15, 33, 55, 165
508 : 1, 2, 4, 127, 254, 508
670 : 1, 2, 5, 10, 67, 134, 335, 670
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,987,165,508,670, is 1.
Now, the common factors can be found like this.
517:11x 47
987:3x 7x 47
165:3x 5x 11
508:2x 2x 127
670:2x 5x 67
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 11x 47 = 15510
Therefore, the value for common factors is 15510.
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 = 28656962472600/(1x15510)
LCM = 28656962472600/15510
LCM = 1847644260
Thus, we can understand that the LCM of 517,987,165,508,670 is 1847644260.
