Given numbers are 979,101,781,909,960
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,101,781,909,960 is 20218777920.
Find LCM of 979,101,781,909,960 with Prime Factorization
| 3 | 979, 101, 781, 909, 960 |
| 11 | 979, 101, 781, 303, 320 |
| 101 | 89, 101, 71, 303, 320 |
| 89, 1, 71, 3, 320 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 101 x 89 x 1 x 71 x 3 x 320 = 20218777920
Therefore, the lowest common multiple of 979,101,781,909,960 is 20218777920.
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.
979 x 101 x 781 x 909 x 960 = 67389186807360
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.
979 : 1, 11, 89, 979
101 : 1, 101
781 : 1, 11, 71, 781
909 : 1, 3, 9, 101, 303, 909
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,101,781,909,960, is 1.
Now, the common factors can be found like this.
979:11x 89
101:101
781:11x 71
909:3x 3x 101
960:2x 2x 2x 2x 2x 2x 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.
3x 11x 101 = 3333
Therefore, the value for common factors is 3333.
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 = 67389186807360/(1x3333)
LCM = 67389186807360/3333
LCM = 20218777920
Thus, we can understand that the LCM of 979,101,781,909,960 is 20218777920.
