Given numbers are 731,762,391,409,324
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,762,391,409,324 is 282954921516.
Find LCM of 731,762,391,409,324 with Prime Factorization
2 | 731, 762, 391, 409, 324 |
3 | 731, 381, 391, 409, 162 |
17 | 731, 127, 391, 409, 54 |
43, 127, 23, 409, 54 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 43 x 127 x 23 x 409 x 54 = 282954921516
Therefore, the lowest common multiple of 731,762,391,409,324 is 282954921516.
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 762 x 391 x 409 x 324 = 28861401994632
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
762 : 1, 2, 3, 6, 127, 254, 381, 762
391 : 1, 17, 23, 391
409 : 1, 409
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,762,391,409,324, is 1.
Now, the common factors can be found like this.
731:17x 43
762:2x 3x 127
391:17x 23
409:409
324:2x 2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 28861401994632/(1x102)
LCM = 28861401994632/102
LCM = 282954921516
Thus, we can understand that the LCM of 731,762,391,409,324 is 282954921516.
