Find LCM of 688,968,443,771,123 with Prime Factorization
| 2 | 688, 968, 443, 771, 123 |
| 2 | 344, 484, 443, 771, 123 |
| 2 | 172, 242, 443, 771, 123 |
| 3 | 86, 121, 443, 771, 123 |
| 86, 121, 443, 257, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 86 x 121 x 443 x 257 x 41 = 1165777769904
Therefore, the lowest common multiple of 688,968,443,771,123 is 1165777769904.
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.
688 x 968 x 443 x 771 x 123 = 27978666477696
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
443 : 1, 443
771 : 1, 3, 257, 771
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,968,443,771,123, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
968:2x 2x 2x 11x 11
443:443
771:3x 257
123:3x 41
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 3 = 24
Therefore, the value for common factors is 24.
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 = 27978666477696/(1x24)
LCM = 27978666477696/24
LCM = 1165777769904
Thus, we can understand that the LCM of 688,968,443,771,123 is 1165777769904.
