Given numbers are 731,376,921,209,452
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,376,921,209,452 is 5978463493992.
Find LCM of 731,376,921,209,452 with Prime Factorization
2 | 731, 376, 921, 209, 452 |
2 | 731, 188, 921, 209, 226 |
731, 94, 921, 209, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 731 x 94 x 921 x 209 x 113 = 5978463493992
Therefore, the lowest common multiple of 731,376,921,209,452 is 5978463493992.
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 376 x 921 x 209 x 452 = 23913853975968
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
376 : 1, 2, 4, 8, 47, 94, 188, 376
921 : 1, 3, 307, 921
209 : 1, 11, 19, 209
452 : 1, 2, 4, 113, 226, 452
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,376,921,209,452, is 1.
Now, the common factors can be found like this.
731:17x 43
376:2x 2x 2x 47
921:3x 307
209:11x 19
452:2x 2x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 23913853975968/(1x4)
LCM = 23913853975968/4
LCM = 5978463493992
Thus, we can understand that the LCM of 731,376,921,209,452 is 5978463493992.
