Given numbers are 131,663,119,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,663,119,728 is 4863768.
Find LCM of 131,663,119,728 with Prime Factorization
7 | 131, 663, 119, 728 |
13 | 131, 663, 17, 104 |
17 | 131, 51, 17, 8 |
131, 3, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 17 x 131 x 3 x 1 x 8 = 4863768
Therefore, the lowest common multiple of 131,663,119,728 is 4863768.
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.
131 x 663 x 119 x 728 = 7524249096
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.
131 : 1, 131
663 : 1, 3, 13, 17, 39, 51, 221, 663
119 : 1, 7, 17, 119
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,663,119,728, is 1.
Now, the common factors can be found like this.
131:131
663:3x 13x 17
119:7x 17
728:2x 2x 2x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 13x 17 = 1547
Therefore, the value for common factors is 1547.
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 = 7524249096/(1x1547)
LCM = 7524249096/1547
LCM = 4863768
Thus, we can understand that the LCM of 131,663,119,728 is 4863768.
