Find LCM of 979,216,720,172,882 with Prime Factorization
| 2 | 979, 216, 720, 172, 882 |
| 2 | 979, 108, 360, 86, 441 |
| 2 | 979, 54, 180, 43, 441 |
| 3 | 979, 27, 90, 43, 441 |
| 3 | 979, 9, 30, 43, 147 |
| 979, 3, 10, 43, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 979 x 3 x 10 x 43 x 49 = 4455546480
Therefore, the lowest common multiple of 979,216,720,172,882 is 4455546480.
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 216 x 720 x 172 x 882 = 23097552952320
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
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
172 : 1, 2, 4, 43, 86, 172
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,216,720,172,882, is 1.
Now, the common factors can be found like this.
979:11x 89
216:2x 2x 2x 3x 3x 3
720:2x 2x 2x 2x 3x 3x 5
172:2x 2x 43
882:2x 3x 3x 7x 7
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 2x 2x 3x 3x 3x 3 = 5184
Therefore, the value for common factors is 5184.
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 = 23097552952320/(1x5184)
LCM = 23097552952320/5184
LCM = 4455546480
Thus, we can understand that the LCM of 979,216,720,172,882 is 4455546480.
