The LCM of 772,756,465,105 is 22615740.
Find LCM of 772,756,465,105 with Prime Factorization
| 2 | 772, 756, 465, 105 |
| 2 | 386, 378, 465, 105 |
| 3 | 193, 189, 465, 105 |
| 5 | 193, 63, 155, 35 |
| 7 | 193, 63, 31, 7 |
| 193, 9, 31, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 193 x 9 x 31 x 1 = 22615740
Therefore, the lowest common multiple of 772,756,465,105 is 22615740.
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.
772 x 756 x 465 x 105 = 28495832400
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.
772 : 1, 2, 4, 193, 386, 772
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
465 : 1, 3, 5, 15, 31, 93, 155, 465
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,756,465,105, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
756:2x 2x 3x 3x 3x 7
465:3x 5x 31
105:3x 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 2x 3x 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 28495832400/(1x1260)
LCM = 28495832400/1260
LCM = 22615740
Thus, we can understand that the LCM of 772,756,465,105 is 22615740.
