Find LCM of 756,261,697,604,687 with Prime Factorization
| 2 | 756, 261, 697, 604, 687 |
| 2 | 378, 261, 697, 302, 687 |
| 3 | 189, 261, 697, 151, 687 |
| 3 | 63, 87, 697, 151, 229 |
| 21, 29, 697, 151, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 21 x 29 x 697 x 151 x 229 = 528402667212
Therefore, the lowest common multiple of 756,261,697,604,687 is 528402667212.
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.
756 x 261 x 697 x 604 x 687 = 57067488058896
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
261 : 1, 3, 9, 29, 87, 261
697 : 1, 17, 41, 697
604 : 1, 2, 4, 151, 302, 604
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,261,697,604,687, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
261:3x 3x 29
697:17x 41
604:2x 2x 151
687:3x 229
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 3 = 108
Therefore, the value for common factors is 108.
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 = 57067488058896/(1x108)
LCM = 57067488058896/108
LCM = 528402667212
Thus, we can understand that the LCM of 756,261,697,604,687 is 528402667212.
