Find LCM of 654,420,965,720,193 with Prime Factorization
| 2 | 654, 420, 965, 720, 193 |
| 2 | 327, 210, 965, 360, 193 |
| 3 | 327, 105, 965, 180, 193 |
| 5 | 109, 35, 965, 60, 193 |
| 193 | 109, 7, 193, 12, 193 |
| 109, 7, 1, 12, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 193 x 109 x 7 x 1 x 12 x 1 = 106026480
Therefore, the lowest common multiple of 654,420,965,720,193 is 106026480.
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.
654 x 420 x 965 x 720 x 193 = 36833599152000
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
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
965 : 1, 5, 193, 965
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
193 : 1, 193
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,420,965,720,193, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
420:2x 2x 3x 5x 7
965:5x 193
720:2x 2x 2x 2x 3x 3x 5
193:193
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 3x 5x 5x 193 = 347400
Therefore, the value for common factors is 347400.
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 = 36833599152000/(1x347400)
LCM = 36833599152000/347400
LCM = 106026480
Thus, we can understand that the LCM of 654,420,965,720,193 is 106026480.
