Given numbers are 649,451,556,398
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,451,556,398 is 2944126196.
Find LCM of 649,451,556,398 with Prime Factorization
| 2 | 649, 451, 556, 398 |
| 11 | 649, 451, 278, 199 |
| 59, 41, 278, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 59 x 41 x 278 x 199 = 2944126196
Therefore, the lowest common multiple of 649,451,556,398 is 2944126196.
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 451 x 556 x 398 = 64770776312
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
451 : 1, 11, 41, 451
556 : 1, 2, 4, 139, 278, 556
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,451,556,398, is 1.
Now, the common factors can be found like this.
649:11x 59
451:11x 41
556:2x 2x 139
398:2x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 64770776312/(1x22)
LCM = 64770776312/22
LCM = 2944126196
Thus, we can understand that the LCM of 649,451,556,398 is 2944126196.
