Given numbers are 917,242,459,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,242,459,660 is 1018585260.
Find LCM of 917,242,459,660 with Prime Factorization
| 2 | 917, 242, 459, 660 |
| 3 | 917, 121, 459, 330 |
| 11 | 917, 121, 153, 110 |
| 917, 11, 153, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 917 x 11 x 153 x 10 = 1018585260
Therefore, the lowest common multiple of 917,242,459,660 is 1018585260.
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.
917 x 242 x 459 x 660 = 67226627160
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.
917 : 1, 7, 131, 917
242 : 1, 2, 11, 22, 121, 242
459 : 1, 3, 9, 17, 27, 51, 153, 459
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,242,459,660, is 1.
Now, the common factors can be found like this.
917:7x 131
242:2x 11x 11
459:3x 3x 3x 17
660:2x 2x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 67226627160/(1x66)
LCM = 67226627160/66
LCM = 1018585260
Thus, we can understand that the LCM of 917,242,459,660 is 1018585260.
