Given numbers are 731,905,110,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,905,110,240 is 349301040.
Find LCM of 731,905,110,240 with Prime Factorization
2 | 731, 905, 110, 240 |
5 | 731, 905, 55, 120 |
731, 181, 11, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 731 x 181 x 11 x 24 = 349301040
Therefore, the lowest common multiple of 731,905,110,240 is 349301040.
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 905 x 110 x 240 = 17465052000
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
905 : 1, 5, 181, 905
110 : 1, 2, 5, 10, 11, 22, 55, 110
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,905,110,240, is 1.
Now, the common factors can be found like this.
731:17x 43
905:5x 181
110:2x 5x 11
240:2x 2x 2x 2x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 17465052000/(1x50)
LCM = 17465052000/50
LCM = 349301040
Thus, we can understand that the LCM of 731,905,110,240 is 349301040.
