Find LCM of 751,217,340,836,931 with Prime Factorization
| 2 | 751, 217, 340, 836, 931 |
| 2 | 751, 217, 170, 418, 931 |
| 7 | 751, 217, 85, 209, 931 |
| 19 | 751, 31, 85, 209, 133 |
| 751, 31, 85, 11, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 751 x 31 x 85 x 11 x 7 = 81063045140
Therefore, the lowest common multiple of 751,217,340,836,931 is 81063045140.
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.
751 x 217 x 340 x 836 x 931 = 43125540014480
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.
751 : 1, 751
217 : 1, 7, 31, 217
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,217,340,836,931, is 1.
Now, the common factors can be found like this.
751:751
217:7x 31
340:2x 2x 5x 17
836:2x 2x 11x 19
931:7x 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 2x 7x 19 = 532
Therefore, the value for common factors is 532.
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 = 43125540014480/(1x532)
LCM = 43125540014480/532
LCM = 81063045140
Thus, we can understand that the LCM of 751,217,340,836,931 is 81063045140.
