Find LCM of 748,195,476,705 with Prime Factorization
| 2 | 748, 195, 476, 705 |
| 2 | 374, 195, 238, 705 |
| 3 | 187, 195, 119, 705 |
| 5 | 187, 65, 119, 235 |
| 17 | 187, 13, 119, 47 |
| 11, 13, 7, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 11 x 13 x 7 x 47 = 47987940
Therefore, the lowest common multiple of 748,195,476,705 is 47987940.
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.
748 x 195 x 476 x 705 = 48947698800
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
195 : 1, 3, 5, 13, 15, 39, 65, 195
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,195,476,705, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
195:3x 5x 13
476:2x 2x 7x 17
705:3x 5x 47
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 3x 5x 17 = 1020
Therefore, the value for common factors is 1020.
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 = 48947698800/(1x1020)
LCM = 48947698800/1020
LCM = 47987940
Thus, we can understand that the LCM of 748,195,476,705 is 47987940.
