Given numbers are 695,680,795,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 695,680,795,768 is 480917760.
Find LCM of 695,680,795,768 with Prime Factorization
| 2 | 695, 680, 795, 768 |
| 2 | 695, 340, 795, 384 |
| 2 | 695, 170, 795, 192 |
| 3 | 695, 85, 795, 96 |
| 5 | 695, 85, 265, 32 |
| 139, 17, 53, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 139 x 17 x 53 x 32 = 480917760
Therefore, the lowest common multiple of 695,680,795,768 is 480917760.
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.
695 x 680 x 795 x 768 = 288550656000
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.
695 : 1, 5, 139, 695
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
795 : 1, 3, 5, 15, 53, 159, 265, 795
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 695,680,795,768, is 1.
Now, the common factors can be found like this.
695:5x 139
680:2x 2x 2x 5x 17
795:3x 5x 53
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 288550656000/(1x600)
LCM = 288550656000/600
LCM = 480917760
Thus, we can understand that the LCM of 695,680,795,768 is 480917760.
