Find LCM of 174,378,320,856,140 with Prime Factorization
| 2 | 174, 378, 320, 856, 140 |
| 2 | 87, 189, 160, 428, 70 |
| 2 | 87, 189, 80, 214, 35 |
| 3 | 87, 189, 40, 107, 35 |
| 5 | 29, 63, 40, 107, 35 |
| 7 | 29, 63, 8, 107, 7 |
| 29, 9, 8, 107, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 29 x 9 x 8 x 107 x 1 = 187669440
Therefore, the lowest common multiple of 174,378,320,856,140 is 187669440.
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.
174 x 378 x 320 x 856 x 140 = 2522277273600
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.
174 : 1, 2, 3, 6, 29, 58, 87, 174
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
856 : 1, 2, 4, 8, 107, 214, 428, 856
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 174,378,320,856,140, is 2.
Now, the common factors can be found like this.
174:2x 3x 29
378:2x 3x 3x 3x 7
320:2x 2x 2x 2x 2x 2x 5
856:2x 2x 2x 107
140:2x 2x 5x 7
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 2x 2x 3x 5x 7 = 6720
Therefore, the value for common factors is 6720.
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 = 2522277273600/(2x6720)
LCM = 2522277273600/13440
LCM = 187669440
Thus, we can understand that the LCM of 174,378,320,856,140 is 187669440.
