Given numbers are 146,140,961,780,752
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 146,140,961,780,752 is 72010651440.
Find LCM of 146,140,961,780,752 with Prime Factorization
| 2 | 146, 140, 961, 780, 752 |
| 2 | 73, 70, 961, 390, 376 |
| 5 | 73, 35, 961, 195, 188 |
| 73, 7, 961, 39, 188 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 73 x 7 x 961 x 39 x 188 = 72010651440
Therefore, the lowest common multiple of 146,140,961,780,752 is 72010651440.
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.
146 x 140 x 961 x 780 x 752 = 11521704230400
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.
146 : 1, 2, 73, 146
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
961 : 1, 31, 961
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 146,140,961,780,752, is 1.
Now, the common factors can be found like this.
146:2x 73
140:2x 2x 5x 7
961:31x 31
780:2x 2x 3x 5x 13
752:2x 2x 2x 2x 47
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 5 = 160
Therefore, the value for common factors is 160.
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 = 11521704230400/(1x160)
LCM = 11521704230400/160
LCM = 72010651440
Thus, we can understand that the LCM of 146,140,961,780,752 is 72010651440.
