Given numbers are 455,985,638,773
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,985,638,773 is 44205651490.
Find LCM of 455,985,638,773 with Prime Factorization
| 5 | 455, 985, 638, 773 |
| 91, 197, 638, 773 |
Multiply the prime numbers at the bottom and the left side.
5 x 91 x 197 x 638 x 773 = 44205651490
Therefore, the lowest common multiple of 455,985,638,773 is 44205651490.
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.
455 x 985 x 638 x 773 = 221028257450
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
985 : 1, 5, 197, 985
638 : 1, 2, 11, 22, 29, 58, 319, 638
773 : 1, 773
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,985,638,773, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
985:5x 197
638:2x 11x 29
773:773
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 221028257450/(1x5)
LCM = 221028257450/5
LCM = 44205651490
Thus, we can understand that the LCM of 455,985,638,773 is 44205651490.
