Find LCM of 689,924,239,968,431 with Prime Factorization
| 2 | 689, 924, 239, 968, 431 |
| 2 | 689, 462, 239, 484, 431 |
| 11 | 689, 231, 239, 242, 431 |
| 689, 21, 239, 22, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 689 x 21 x 239 x 22 x 431 = 1442743229928
Therefore, the lowest common multiple of 689,924,239,968,431 is 1442743229928.
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 924 x 239 x 968 x 431 = 63480702116832
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
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
239 : 1, 239
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,924,239,968,431, is 1.
Now, the common factors can be found like this.
689:13x 53
924:2x 2x 3x 7x 11
239:239
968:2x 2x 2x 11x 11
431:431
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 11 = 44
Therefore, the value for common factors is 44.
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 = 63480702116832/(1x44)
LCM = 63480702116832/44
LCM = 1442743229928
Thus, we can understand that the LCM of 689,924,239,968,431 is 1442743229928.
