Given numbers are 134,681,702,728,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 134,681,702,728,771 is 76829662728.
Find LCM of 134,681,702,728,771 with Prime Factorization
| 2 | 134, 681, 702, 728, 771 |
| 3 | 67, 681, 351, 364, 771 |
| 13 | 67, 227, 117, 364, 257 |
| 67, 227, 9, 28, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 67 x 227 x 9 x 28 x 257 = 76829662728
Therefore, the lowest common multiple of 134,681,702,728,771 is 76829662728.
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.
134 x 681 x 702 x 728 x 771 = 35956282156704
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.
134 : 1, 2, 67, 134
681 : 1, 3, 227, 681
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 134,681,702,728,771, is 1.
Now, the common factors can be found like this.
134:2x 67
681:3x 227
702:2x 3x 3x 3x 13
728:2x 2x 2x 7x 13
771:3x 257
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 13 = 468
Therefore, the value for common factors is 468.
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 = 35956282156704/(1x468)
LCM = 35956282156704/468
LCM = 76829662728
Thus, we can understand that the LCM of 134,681,702,728,771 is 76829662728.
