Find LCM of 569,360,644,940,981 with Prime Factorization
| 2 | 569, 360, 644, 940, 981 |
| 2 | 569, 180, 322, 470, 981 |
| 3 | 569, 90, 161, 235, 981 |
| 3 | 569, 30, 161, 235, 327 |
| 5 | 569, 10, 161, 235, 109 |
| 569, 2, 161, 47, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 569 x 2 x 161 x 47 x 109 = 168952646520
Therefore, the lowest common multiple of 569,360,644,940,981 is 168952646520.
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.
569 x 360 x 644 x 940 x 981 = 121645905494400
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.
569 : 1, 569
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
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 569,360,644,940,981, is 1.
Now, the common factors can be found like this.
569:569
360:2x 2x 2x 3x 3x 5
644:2x 2x 7x 23
940:2x 2x 5x 47
981:3x 3x 109
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 = 121645905494400/(1x720)
LCM = 121645905494400/720
LCM = 168952646520
Thus, we can understand that the LCM of 569,360,644,940,981 is 168952646520.
