Given numbers are 649,196,428,359
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,196,428,359 is 4886287252.
Find LCM of 649,196,428,359 with Prime Factorization
| 2 | 649, 196, 428, 359 |
| 2 | 649, 98, 214, 359 |
| 649, 49, 107, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 649 x 49 x 107 x 359 = 4886287252
Therefore, the lowest common multiple of 649,196,428,359 is 4886287252.
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.
649 x 196 x 428 x 359 = 19545149008
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.
649 : 1, 11, 59, 649
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
428 : 1, 2, 4, 107, 214, 428
359 : 1, 359
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,196,428,359, is 1.
Now, the common factors can be found like this.
649:11x 59
196:2x 2x 7x 7
428:2x 2x 107
359:359
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 = 19545149008/(1x4)
LCM = 19545149008/4
LCM = 4886287252
Thus, we can understand that the LCM of 649,196,428,359 is 4886287252.
