Find LCM of 561,680,702,901,680 with Prime Factorization
| 2 | 561, 680, 702, 901, 680 |
| 2 | 561, 340, 351, 901, 340 |
| 2 | 561, 170, 351, 901, 170 |
| 3 | 561, 85, 351, 901, 85 |
| 5 | 187, 85, 117, 901, 85 |
| 17 | 187, 17, 117, 901, 17 |
| 11, 1, 117, 53, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 17 x 11 x 1 x 117 x 53 x 1 = 139150440
Therefore, the lowest common multiple of 561,680,702,901,680 is 139150440.
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.
561 x 680 x 702 x 901 x 680 = 164075066812800
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
901 : 1, 17, 53, 901
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,680,702,901,680, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
680:2x 2x 2x 5x 17
702:2x 3x 3x 3x 13
901:17x 53
680:2x 2x 2x 5x 17
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 2x 2x 3x 5x 17x 17x 17 = 1179120
Therefore, the value for common factors is 1179120.
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 = 164075066812800/(1x1179120)
LCM = 164075066812800/1179120
LCM = 139150440
Thus, we can understand that the LCM of 561,680,702,901,680 is 139150440.
