Find LCM of 927,210,645,791,981 with Prime Factorization
| 3 | 927, 210, 645, 791, 981 |
| 3 | 309, 70, 215, 791, 327 |
| 5 | 103, 70, 215, 791, 109 |
| 7 | 103, 14, 43, 791, 109 |
| 103, 2, 43, 113, 109 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 103 x 2 x 43 x 113 x 109 = 34367755590
Therefore, the lowest common multiple of 927,210,645,791,981 is 34367755590.
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.
927 x 210 x 645 x 791 x 981 = 97432587097650
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.
927 : 1, 3, 9, 103, 309, 927
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
645 : 1, 3, 5, 15, 43, 129, 215, 645
791 : 1, 7, 113, 791
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 927,210,645,791,981, is 1.
Now, the common factors can be found like this.
927:3x 3x 103
210:2x 3x 5x 7
645:3x 5x 43
791:7x 113
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5x 7 = 2835
Therefore, the value for common factors is 2835.
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 = 97432587097650/(1x2835)
LCM = 97432587097650/2835
LCM = 34367755590
Thus, we can understand that the LCM of 927,210,645,791,981 is 34367755590.
