Find LCM of 762,783,315,901,140 with Prime Factorization
| 2 | 762, 783, 315, 901, 140 |
| 3 | 381, 783, 315, 901, 70 |
| 3 | 127, 261, 105, 901, 70 |
| 5 | 127, 87, 35, 901, 70 |
| 7 | 127, 87, 7, 901, 14 |
| 127, 87, 1, 901, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 127 x 87 x 1 x 901 x 2 = 12543487740
Therefore, the lowest common multiple of 762,783,315,901,140 is 12543487740.
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.
762 x 783 x 315 x 901 x 140 = 23707191828600
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
783 : 1, 3, 9, 27, 29, 87, 261, 783
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
901 : 1, 17, 53, 901
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,783,315,901,140, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
783:3x 3x 3x 29
315:3x 3x 5x 7
901:17x 53
140:2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 7 = 1890
Therefore, the value for common factors is 1890.
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 = 23707191828600/(1x1890)
LCM = 23707191828600/1890
LCM = 12543487740
Thus, we can understand that the LCM of 762,783,315,901,140 is 12543487740.
