Find LCM of 723,965,657,702,949 with Prime Factorization
| 3 | 723, 965, 657, 702, 949 |
| 3 | 241, 965, 219, 234, 949 |
| 13 | 241, 965, 73, 78, 949 |
| 73 | 241, 965, 73, 6, 73 |
| 241, 965, 1, 6, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 73 x 241 x 965 x 1 x 6 x 1 = 11918025990
Therefore, the lowest common multiple of 723,965,657,702,949 is 11918025990.
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.
723 x 965 x 657 x 702 x 949 = 305375579941770
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.
723 : 1, 3, 241, 723
965 : 1, 5, 193, 965
657 : 1, 3, 9, 73, 219, 657
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
949 : 1, 13, 73, 949
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,965,657,702,949, is 1.
Now, the common factors can be found like this.
723:3x 241
965:5x 193
657:3x 3x 73
702:2x 3x 3x 3x 13
949:13x 73
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 13x 73 = 25623
Therefore, the value for common factors is 25623.
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 = 305375579941770/(1x25623)
LCM = 305375579941770/25623
LCM = 11918025990
Thus, we can understand that the LCM of 723,965,657,702,949 is 11918025990.
