Given numbers are 766,918,221,942,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,918,221,942,917 is 658042275618.
Find LCM of 766,918,221,942,917 with Prime Factorization
| 2 | 766, 918, 221, 942, 917 |
| 3 | 383, 459, 221, 471, 917 |
| 17 | 383, 153, 221, 157, 917 |
| 383, 9, 13, 157, 917 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 383 x 9 x 13 x 157 x 917 = 658042275618
Therefore, the lowest common multiple of 766,918,221,942,917 is 658042275618.
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.
766 x 918 x 221 x 942 x 917 = 134240624226072
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.
766 : 1, 2, 383, 766
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
221 : 1, 13, 17, 221
942 : 1, 2, 3, 6, 157, 314, 471, 942
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,918,221,942,917, is 1.
Now, the common factors can be found like this.
766:2x 383
918:2x 3x 3x 3x 17
221:13x 17
942:2x 3x 157
917:7x 131
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 3x 17 = 204
Therefore, the value for common factors is 204.
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 = 134240624226072/(1x204)
LCM = 134240624226072/204
LCM = 658042275618
Thus, we can understand that the LCM of 766,918,221,942,917 is 658042275618.
