Given numbers are 771,460,156,360
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,460,156,360 is 27663480.
Find LCM of 771,460,156,360 with Prime Factorization
| 2 | 771, 460, 156, 360 |
| 2 | 771, 230, 78, 180 |
| 3 | 771, 115, 39, 90 |
| 5 | 257, 115, 13, 30 |
| 257, 23, 13, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 257 x 23 x 13 x 6 = 27663480
Therefore, the lowest common multiple of 771,460,156,360 is 27663480.
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.
771 x 460 x 156 x 360 = 19917705600
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.
771 : 1, 3, 257, 771
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,460,156,360, is 1.
Now, the common factors can be found like this.
771:3x 257
460:2x 2x 5x 23
156:2x 2x 3x 13
360:2x 2x 2x 3x 3x 5
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 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 19917705600/(1x720)
LCM = 19917705600/720
LCM = 27663480
Thus, we can understand that the LCM of 771,460,156,360 is 27663480.
