Given numbers are 605,972,960,965
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,972,960,965 is 1815929280.
Find LCM of 605,972,960,965 with Prime Factorization
| 2 | 605, 972, 960, 965 |
| 2 | 605, 486, 480, 965 |
| 3 | 605, 243, 240, 965 |
| 5 | 605, 81, 80, 965 |
| 121, 81, 16, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 121 x 81 x 16 x 193 = 1815929280
Therefore, the lowest common multiple of 605,972,960,965 is 1815929280.
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.
605 x 972 x 960 x 965 = 544778784000
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.
605 : 1, 5, 11, 55, 121, 605
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
965 : 1, 5, 193, 965
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,972,960,965, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
972:2x 2x 3x 3x 3x 3x 3
960:2x 2x 2x 2x 2x 2x 3x 5
965:5x 193
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 544778784000/(1x300)
LCM = 544778784000/300
LCM = 1815929280
Thus, we can understand that the LCM of 605,972,960,965 is 1815929280.
