The LCM of 731,680,824,262 is 394535320.
Find LCM of 731,680,824,262 with Prime Factorization
| 2 | 731, 680, 824, 262 |
| 2 | 731, 340, 412, 131 |
| 2 | 731, 170, 206, 131 |
| 17 | 731, 85, 103, 131 |
| 43, 5, 103, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 43 x 5 x 103 x 131 = 394535320
Therefore, the lowest common multiple of 731,680,824,262 is 394535320.
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.
731 x 680 x 824 x 262 = 107313607040
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.
731 : 1, 17, 43, 731
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
824 : 1, 2, 4, 8, 103, 206, 412, 824
262 : 1, 2, 131, 262
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,680,824,262, is 1.
Now, the common factors can be found like this.
731:17x 43
680:2x 2x 2x 5x 17
824:2x 2x 2x 103
262:2x 131
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 2x 17 = 272
Therefore, the value for common factors is 272.
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 = 107313607040/(1x272)
LCM = 107313607040/272
LCM = 394535320
Thus, we can understand that the LCM of 731,680,824,262 is 394535320.
