The LCM of 434,157,360,648 is 110383560.
Find LCM of 434,157,360,648 with Prime Factorization
| 2 | 434, 157, 360, 648 |
| 2 | 217, 157, 180, 324 |
| 2 | 217, 157, 90, 162 |
| 3 | 217, 157, 45, 81 |
| 3 | 217, 157, 15, 27 |
| 217, 157, 5, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 217 x 157 x 5 x 9 = 110383560
Therefore, the lowest common multiple of 434,157,360,648 is 110383560.
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.
434 x 157 x 360 x 648 = 15895232640
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.
434 : 1, 2, 7, 14, 31, 62, 217, 434
157 : 1, 157
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
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,157,360,648, is 1.
Now, the common factors can be found like this.
434:2x 7x 31
157:157
360:2x 2x 2x 3x 3x 5
648:2x 2x 2x 3x 3x 3x 3
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 3 = 144
Therefore, the value for common factors is 144.
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 = 15895232640/(1x144)
LCM = 15895232640/144
LCM = 110383560
Thus, we can understand that the LCM of 434,157,360,648 is 110383560.
