Given numbers are 191,581,128,646,382
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,581,128,646,382 is 4587985024.
Find LCM of 191,581,128,646,382 with Prime Factorization
2 | 191, 581, 128, 646, 382 |
191 | 191, 581, 64, 323, 191 |
1, 581, 64, 323, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 191 x 1 x 581 x 64 x 323 x 1 = 4587985024
Therefore, the lowest common multiple of 191,581,128,646,382 is 4587985024.
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.
191 x 581 x 128 x 646 x 382 = 3505220558336
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.
191 : 1, 191
581 : 1, 7, 83, 581
128 : 1, 2, 4, 8, 16, 32, 64, 128
646 : 1, 2, 17, 19, 34, 38, 323, 646
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,581,128,646,382, is 1.
Now, the common factors can be found like this.
191:191
581:7x 83
128:2x 2x 2x 2x 2x 2x 2
646:2x 17x 19
382:2x 191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 191 = 764
Therefore, the value for common factors is 764.
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 = 3505220558336/(1x764)
LCM = 3505220558336/764
LCM = 4587985024
Thus, we can understand that the LCM of 191,581,128,646,382 is 4587985024.
