Given numbers are 694,847,253,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 694,847,253,418 is 256876466.
Find LCM of 694,847,253,418 with Prime Factorization
| 2 | 694, 847, 253, 418 |
| 11 | 347, 847, 253, 209 |
| 347, 77, 23, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 347 x 77 x 23 x 19 = 256876466
Therefore, the lowest common multiple of 694,847,253,418 is 256876466.
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.
694 x 847 x 253 x 418 = 62164104772
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.
694 : 1, 2, 347, 694
847 : 1, 7, 11, 77, 121, 847
253 : 1, 11, 23, 253
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,847,253,418, is 1.
Now, the common factors can be found like this.
694:2x 347
847:7x 11x 11
253:11x 23
418:2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 62164104772/(1x242)
LCM = 62164104772/242
LCM = 256876466
Thus, we can understand that the LCM of 694,847,253,418 is 256876466.
