Given numbers are 921,873,354,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,873,354,649 is 347878278.
Find LCM of 921,873,354,649 with Prime Factorization
| 3 | 921, 873, 354, 649 |
| 59 | 307, 291, 118, 649 |
| 307, 291, 2, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 59 x 307 x 291 x 2 x 11 = 347878278
Therefore, the lowest common multiple of 921,873,354,649 is 347878278.
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.
921 x 873 x 354 x 649 = 184723365618
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.
921 : 1, 3, 307, 921
873 : 1, 3, 9, 97, 291, 873
354 : 1, 2, 3, 6, 59, 118, 177, 354
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,873,354,649, is 1.
Now, the common factors can be found like this.
921:3x 307
873:3x 3x 97
354:2x 3x 59
649:11x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 59 = 531
Therefore, the value for common factors is 531.
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 = 184723365618/(1x531)
LCM = 184723365618/531
LCM = 347878278
Thus, we can understand that the LCM of 921,873,354,649 is 347878278.
