Find LCM of 384,865,221,420,970 with Prime Factorization
2 | 384, 865, 221, 420, 970 |
2 | 192, 865, 221, 210, 485 |
3 | 96, 865, 221, 105, 485 |
5 | 32, 865, 221, 35, 485 |
32, 173, 221, 7, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 32 x 173 x 221 x 7 x 97 = 49843597440
Therefore, the lowest common multiple of 384,865,221,420,970 is 49843597440.
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.
384 x 865 x 221 x 420 x 970 = 29906158464000
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.
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
865 : 1, 5, 173, 865
221 : 1, 13, 17, 221
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
970 : 1, 2, 5, 10, 97, 194, 485, 970
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 384,865,221,420,970, is 1.
Now, the common factors can be found like this.
384:2x 2x 2x 2x 2x 2x 2x 3
865:5x 173
221:13x 17
420:2x 2x 3x 5x 7
970:2x 5x 97
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 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 29906158464000/(1x600)
LCM = 29906158464000/600
LCM = 49843597440
Thus, we can understand that the LCM of 384,865,221,420,970 is 49843597440.
