Find LCM of 693,438,276,261,931 with Prime Factorization
| 2 | 693, 438, 276, 261, 931 |
| 3 | 693, 219, 138, 261, 931 |
| 3 | 231, 73, 46, 87, 931 |
| 7 | 77, 73, 46, 29, 931 |
| 11, 73, 46, 29, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 11 x 73 x 46 x 29 x 133 = 17951203116
Therefore, the lowest common multiple of 693,438,276,261,931 is 17951203116.
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.
693 x 438 x 276 x 261 x 931 = 20356664333544
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
438 : 1, 2, 3, 6, 73, 146, 219, 438
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
261 : 1, 3, 9, 29, 87, 261
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 693,438,276,261,931, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
438:2x 3x 73
276:2x 2x 3x 23
261:3x 3x 29
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 3x 3x 3x 3x 7 = 1134
Therefore, the value for common factors is 1134.
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 = 20356664333544/(1x1134)
LCM = 20356664333544/1134
LCM = 17951203116
Thus, we can understand that the LCM of 693,438,276,261,931 is 17951203116.
