Given numbers are 140,752,746,664,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,752,746,664,678 is 276231058320.
Find LCM of 140,752,746,664,678 with Prime Factorization
| 2 | 140, 752, 746, 664, 678 |
| 2 | 70, 376, 373, 332, 339 |
| 2 | 35, 188, 373, 166, 339 |
| 35, 94, 373, 83, 339 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 35 x 94 x 373 x 83 x 339 = 276231058320
Therefore, the lowest common multiple of 140,752,746,664,678 is 276231058320.
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.
140 x 752 x 746 x 664 x 678 = 35357575464960
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
746 : 1, 2, 373, 746
664 : 1, 2, 4, 8, 83, 166, 332, 664
678 : 1, 2, 3, 6, 113, 226, 339, 678
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,752,746,664,678, is 2.
Now, the common factors can be found like this.
140:2x 2x 5x 7
752:2x 2x 2x 2x 47
746:2x 373
664:2x 2x 2x 83
678:2x 3x 113
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 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 35357575464960/(2x64)
LCM = 35357575464960/128
LCM = 276231058320
Thus, we can understand that the LCM of 140,752,746,664,678 is 276231058320.
