Find LCM of 547,147,770,816,690 with Prime Factorization
| 2 | 547, 147, 770, 816, 690 |
| 3 | 547, 147, 385, 408, 345 |
| 5 | 547, 49, 385, 136, 115 |
| 7 | 547, 49, 77, 136, 23 |
| 547, 7, 11, 136, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 547 x 7 x 11 x 136 x 23 = 27667128720
Therefore, the lowest common multiple of 547,147,770,816,690 is 27667128720.
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.
547 x 147 x 770 x 816 x 690 = 34860582187200
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.
547 : 1, 547
147 : 1, 3, 7, 21, 49, 147
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 547,147,770,816,690, is 1.
Now, the common factors can be found like this.
547:547
147:3x 7x 7
770:2x 5x 7x 11
816:2x 2x 2x 2x 3x 17
690:2x 3x 5x 23
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 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 34860582187200/(1x1260)
LCM = 34860582187200/1260
LCM = 27667128720
Thus, we can understand that the LCM of 547,147,770,816,690 is 27667128720.
