Find LCM of 949,628,765,868,731 with Prime Factorization
| 2 | 949, 628, 765, 868, 731 |
| 2 | 949, 314, 765, 434, 731 |
| 17 | 949, 157, 765, 217, 731 |
| 949, 157, 45, 217, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 949 x 157 x 45 x 217 x 43 = 4254176269980
Therefore, the lowest common multiple of 949,628,765,868,731 is 4254176269980.
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.
949 x 628 x 765 x 868 x 731 = 289283986358640
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.
949 : 1, 13, 73, 949
628 : 1, 2, 4, 157, 314, 628
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 949,628,765,868,731, is 1.
Now, the common factors can be found like this.
949:13x 73
628:2x 2x 157
765:3x 3x 5x 17
868:2x 2x 7x 31
731:17x 43
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 17 = 68
Therefore, the value for common factors is 68.
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 = 289283986358640/(1x68)
LCM = 289283986358640/68
LCM = 4254176269980
Thus, we can understand that the LCM of 949,628,765,868,731 is 4254176269980.
