The LCM of 771,804,140,469 is 7231980.
Find LCM of 771,804,140,469 with Prime Factorization
| 2 | 771, 804, 140, 469 |
| 2 | 771, 402, 70, 469 |
| 3 | 771, 201, 35, 469 |
| 7 | 257, 67, 35, 469 |
| 67 | 257, 67, 5, 67 |
| 257, 1, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 67 x 257 x 1 x 5 x 1 = 7231980
Therefore, the lowest common multiple of 771,804,140,469 is 7231980.
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.
771 x 804 x 140 x 469 = 40701583440
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.
771 : 1, 3, 257, 771
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
469 : 1, 7, 67, 469
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,804,140,469, is 1.
Now, the common factors can be found like this.
771:3x 257
804:2x 2x 3x 67
140:2x 2x 5x 7
469:7x 67
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 7x 67 = 5628
Therefore, the value for common factors is 5628.
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 = 40701583440/(1x5628)
LCM = 40701583440/5628
LCM = 7231980
Thus, we can understand that the LCM of 771,804,140,469 is 7231980.
