Find LCM of 188,728,145,705,154 with Prime Factorization
| 2 | 188, 728, 145, 705, 154 |
| 2 | 94, 364, 145, 705, 77 |
| 5 | 47, 182, 145, 705, 77 |
| 7 | 47, 182, 29, 141, 77 |
| 47 | 47, 26, 29, 141, 11 |
| 1, 26, 29, 3, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 47 x 1 x 26 x 29 x 3 x 11 = 163723560
Therefore, the lowest common multiple of 188,728,145,705,154 is 163723560.
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.
188 x 728 x 145 x 705 x 154 = 2154602049600
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.
188 : 1, 2, 4, 47, 94, 188
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
145 : 1, 5, 29, 145
705 : 1, 3, 5, 15, 47, 141, 235, 705
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 188,728,145,705,154, is 1.
Now, the common factors can be found like this.
188:2x 2x 47
728:2x 2x 2x 7x 13
145:5x 29
705:3x 5x 47
154:2x 7x 11
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 5x 7x 47 = 13160
Therefore, the value for common factors is 13160.
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 = 2154602049600/(1x13160)
LCM = 2154602049600/13160
LCM = 163723560
Thus, we can understand that the LCM of 188,728,145,705,154 is 163723560.
