Given numbers are 749,381,856,305
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,381,856,305 is 696300360.
Find LCM of 749,381,856,305 with Prime Factorization
107 | 749, 381, 856, 305 |
7, 381, 8, 305 |
Multiply the prime numbers at the bottom and the left side.
107 x 7 x 381 x 8 x 305 = 696300360
Therefore, the lowest common multiple of 749,381,856,305 is 696300360.
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.
749 x 381 x 856 x 305 = 74504138520
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.
749 : 1, 7, 107, 749
381 : 1, 3, 127, 381
856 : 1, 2, 4, 8, 107, 214, 428, 856
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,381,856,305, is 1.
Now, the common factors can be found like this.
749:7x 107
381:3x 127
856:2x 2x 2x 107
305:5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
107 = 107
Therefore, the value for common factors is 107.
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 = 74504138520/(1x107)
LCM = 74504138520/107
LCM = 696300360
Thus, we can understand that the LCM of 749,381,856,305 is 696300360.
