Find LCM of 689,902,546,840,674 with Prime Factorization
| 2 | 689, 902, 546, 840, 674 |
| 3 | 689, 451, 273, 420, 337 |
| 7 | 689, 451, 91, 140, 337 |
| 13 | 689, 451, 13, 20, 337 |
| 53, 451, 1, 20, 337 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 53 x 451 x 1 x 20 x 337 = 87963996120
Therefore, the lowest common multiple of 689,902,546,840,674 is 87963996120.
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.
689 x 902 x 546 x 840 x 674 = 192113367526080
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.
689 : 1, 13, 53, 689
902 : 1, 2, 11, 22, 41, 82, 451, 902
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
674 : 1, 2, 337, 674
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,902,546,840,674, is 1.
Now, the common factors can be found like this.
689:13x 53
902:2x 11x 41
546:2x 3x 7x 13
840:2x 2x 2x 3x 5x 7
674:2x 337
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 2x 3x 7x 13 = 2184
Therefore, the value for common factors is 2184.
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 = 192113367526080/(1x2184)
LCM = 192113367526080/2184
LCM = 87963996120
Thus, we can understand that the LCM of 689,902,546,840,674 is 87963996120.
