Find LCM of 140,740,511,148,856 with Prime Factorization
| 2 | 140, 740, 511, 148, 856 |
| 2 | 70, 370, 511, 74, 428 |
| 5 | 35, 185, 511, 37, 214 |
| 7 | 7, 37, 511, 37, 214 |
| 37 | 1, 37, 73, 37, 214 |
| 1, 1, 73, 1, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 37 x 1 x 1 x 73 x 1 x 214 = 80921960
Therefore, the lowest common multiple of 140,740,511,148,856 is 80921960.
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.
140 x 740 x 511 x 148 x 856 = 6706812044800
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
511 : 1, 7, 73, 511
148 : 1, 2, 4, 37, 74, 148
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,740,511,148,856, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
740:2x 2x 5x 37
511:7x 73
148:2x 2x 37
856:2x 2x 2x 107
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 5x 7x 37 = 82880
Therefore, the value for common factors is 82880.
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 = 6706812044800/(1x82880)
LCM = 6706812044800/82880
LCM = 80921960
Thus, we can understand that the LCM of 140,740,511,148,856 is 80921960.
