The LCM of 693,831,756,119 is 39160044.
Find LCM of 693,831,756,119 with Prime Factorization
| 3 | 693, 831, 756, 119 |
| 3 | 231, 277, 252, 119 |
| 7 | 77, 277, 84, 119 |
| 11, 277, 12, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 11 x 277 x 12 x 17 = 39160044
Therefore, the lowest common multiple of 693,831,756,119 is 39160044.
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.
693 x 831 x 756 x 119 = 51808738212
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
831 : 1, 3, 277, 831
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
119 : 1, 7, 17, 119
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,831,756,119, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
831:3x 277
756:2x 2x 3x 3x 3x 7
119:7x 17
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 3x 7x 7 = 1323
Therefore, the value for common factors is 1323.
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 = 51808738212/(1x1323)
LCM = 51808738212/1323
LCM = 39160044
Thus, we can understand that the LCM of 693,831,756,119 is 39160044.
