Given numbers are 360,865,634,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 360,865,634,781 is 15419095560.
Find LCM of 360,865,634,781 with Prime Factorization
| 2 | 360, 865, 634, 781 |
| 5 | 180, 865, 317, 781 |
| 36, 173, 317, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 36 x 173 x 317 x 781 = 15419095560
Therefore, the lowest common multiple of 360,865,634,781 is 15419095560.
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.
360 x 865 x 634 x 781 = 154190955600
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.
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
865 : 1, 5, 173, 865
634 : 1, 2, 317, 634
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 360,865,634,781, is 1.
Now, the common factors can be found like this.
360:2x 2x 2x 3x 3x 5
865:5x 173
634:2x 317
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 154190955600/(1x10)
LCM = 154190955600/10
LCM = 15419095560
Thus, we can understand that the LCM of 360,865,634,781 is 15419095560.
