Given numbers are 768,990,712,695
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,990,712,695 is 1567653120.
Find LCM of 768,990,712,695 with Prime Factorization
| 2 | 768, 990, 712, 695 |
| 2 | 384, 495, 356, 695 |
| 2 | 192, 495, 178, 695 |
| 3 | 96, 495, 89, 695 |
| 5 | 32, 165, 89, 695 |
| 32, 33, 89, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 32 x 33 x 89 x 139 = 1567653120
Therefore, the lowest common multiple of 768,990,712,695 is 1567653120.
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.
768 x 990 x 712 x 695 = 376236748800
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
712 : 1, 2, 4, 8, 89, 178, 356, 712
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,990,712,695, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
990:2x 3x 3x 5x 11
712:2x 2x 2x 89
695:5x 139
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 5 = 240
Therefore, the value for common factors is 240.
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 = 376236748800/(1x240)
LCM = 376236748800/240
LCM = 1567653120
Thus, we can understand that the LCM of 768,990,712,695 is 1567653120.
