Find LCM of 147,310,561,612,905 with Prime Factorization
| 2 | 147, 310, 561, 612, 905 |
| 3 | 147, 155, 561, 306, 905 |
| 5 | 49, 155, 187, 102, 905 |
| 17 | 49, 31, 187, 102, 181 |
| 49, 31, 11, 6, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 49 x 31 x 11 x 6 x 181 = 9254446740
Therefore, the lowest common multiple of 147,310,561,612,905 is 9254446740.
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.
147 x 310 x 561 x 612 x 905 = 14159303512200
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.
147 : 1, 3, 7, 21, 49, 147
310 : 1, 2, 5, 10, 31, 62, 155, 310
561 : 1, 3, 11, 17, 33, 51, 187, 561
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 147,310,561,612,905, is 1.
Now, the common factors can be found like this.
147:3x 7x 7
310:2x 5x 31
561:3x 11x 17
612:2x 2x 3x 3x 17
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 17 = 1530
Therefore, the value for common factors is 1530.
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 = 14159303512200/(1x1530)
LCM = 14159303512200/1530
LCM = 9254446740
Thus, we can understand that the LCM of 147,310,561,612,905 is 9254446740.
