Find LCM of 769,343,407,546,666 with Prime Factorization
| 2 | 769, 343, 407, 546, 666 |
| 3 | 769, 343, 407, 273, 333 |
| 7 | 769, 343, 407, 91, 111 |
| 37 | 769, 49, 407, 13, 111 |
| 769, 49, 11, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 37 x 769 x 49 x 11 x 13 x 3 = 25120641546
Therefore, the lowest common multiple of 769,343,407,546,666 is 25120641546.
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.
769 x 343 x 407 x 546 x 666 = 39037476962484
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.
769 : 1, 769
343 : 1, 7, 49, 343
407 : 1, 11, 37, 407
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,343,407,546,666, is 1.
Now, the common factors can be found like this.
769:769
343:7x 7x 7
407:11x 37
546:2x 3x 7x 13
666:2x 3x 3x 37
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 7x 37 = 1554
Therefore, the value for common factors is 1554.
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 = 39037476962484/(1x1554)
LCM = 39037476962484/1554
LCM = 25120641546
Thus, we can understand that the LCM of 769,343,407,546,666 is 25120641546.
