Given numbers are 731,281,374,902,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,281,374,902,945 is 175090282290.
Find LCM of 731,281,374,902,945 with Prime Factorization
| 2 | 731, 281, 374, 902, 945 |
| 11 | 731, 281, 187, 451, 945 |
| 17 | 731, 281, 17, 41, 945 |
| 43, 281, 1, 41, 945 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 43 x 281 x 1 x 41 x 945 = 175090282290
Therefore, the lowest common multiple of 731,281,374,902,945 is 175090282290.
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.
731 x 281 x 374 x 902 x 945 = 65483765576460
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.
731 : 1, 17, 43, 731
281 : 1, 281
374 : 1, 2, 11, 17, 22, 34, 187, 374
902 : 1, 2, 11, 22, 41, 82, 451, 902
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,281,374,902,945, is 1.
Now, the common factors can be found like this.
731:17x 43
281:281
374:2x 11x 17
902:2x 11x 41
945:3x 3x 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 11x 17 = 374
Therefore, the value for common factors is 374.
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 = 65483765576460/(1x374)
LCM = 65483765576460/374
LCM = 175090282290
Thus, we can understand that the LCM of 731,281,374,902,945 is 175090282290.
