Find LCM of 695,895,756,441 with Prime Factorization
| 3 | 695, 895, 756, 441 |
| 3 | 695, 895, 252, 147 |
| 5 | 695, 895, 84, 49 |
| 7 | 139, 179, 84, 49 |
| 139, 179, 12, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 139 x 179 x 12 x 7 = 658351260
Therefore, the lowest common multiple of 695,895,756,441 is 658351260.
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 895 x 756 x 441 = 207380646900
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
895 : 1, 5, 179, 895
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
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 695,895,756,441, is 1.
Now, the common factors can be found like this.
695:5x 139
895:5x 179
756:2x 2x 3x 3x 3x 7
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 207380646900/(1x315)
LCM = 207380646900/315
LCM = 658351260
Thus, we can understand that the LCM of 695,895,756,441 is 658351260.
