Given numbers are 451,627,393,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,627,393,641 is 2158642497.
Find LCM of 451,627,393,641 with Prime Factorization
| 3 | 451, 627, 393, 641 |
| 11 | 451, 209, 131, 641 |
| 41, 19, 131, 641 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 41 x 19 x 131 x 641 = 2158642497
Therefore, the lowest common multiple of 451,627,393,641 is 2158642497.
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.
451 x 627 x 393 x 641 = 71235202401
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.
451 : 1, 11, 41, 451
627 : 1, 3, 11, 19, 33, 57, 209, 627
393 : 1, 3, 131, 393
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,627,393,641, is 1.
Now, the common factors can be found like this.
451:11x 41
627:3x 11x 19
393:3x 131
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 71235202401/(1x33)
LCM = 71235202401/33
LCM = 2158642497
Thus, we can understand that the LCM of 451,627,393,641 is 2158642497.
