Given numbers are 181,648,628,489,757
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 181,648,628,489,757 is 2272148526456.
Find LCM of 181,648,628,489,757 with Prime Factorization
2 | 181, 648, 628, 489, 757 |
2 | 181, 324, 314, 489, 757 |
3 | 181, 162, 157, 489, 757 |
181, 54, 157, 163, 757 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 181 x 54 x 157 x 163 x 757 = 2272148526456
Therefore, the lowest common multiple of 181,648,628,489,757 is 2272148526456.
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.
181 x 648 x 628 x 489 x 757 = 27265782317472
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.
181 : 1, 181
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
628 : 1, 2, 4, 157, 314, 628
489 : 1, 3, 163, 489
757 : 1, 757
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,648,628,489,757, is 1.
Now, the common factors can be found like this.
181:181
648:2x 2x 2x 3x 3x 3x 3
628:2x 2x 157
489:3x 163
757:757
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 27265782317472/(1x12)
LCM = 27265782317472/12
LCM = 2272148526456
Thus, we can understand that the LCM of 181,648,628,489,757 is 2272148526456.
