Find LCM of 688,419,424,774,879 with Prime Factorization
| 2 | 688, 419, 424, 774, 879 |
| 2 | 344, 419, 212, 387, 879 |
| 2 | 172, 419, 106, 387, 879 |
| 3 | 86, 419, 53, 387, 879 |
| 43 | 86, 419, 53, 129, 293 |
| 2, 419, 53, 3, 293 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 43 x 2 x 419 x 53 x 3 x 293 = 40289182992
Therefore, the lowest common multiple of 688,419,424,774,879 is 40289182992.
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 419 x 424 x 774 x 879 = 83156873695488
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
419 : 1, 419
424 : 1, 2, 4, 8, 53, 106, 212, 424
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
879 : 1, 3, 293, 879
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,419,424,774,879, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
419:419
424:2x 2x 2x 53
774:2x 3x 3x 43
879:3x 293
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 3x 43 = 2064
Therefore, the value for common factors is 2064.
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 = 83156873695488/(1x2064)
LCM = 83156873695488/2064
LCM = 40289182992
Thus, we can understand that the LCM of 688,419,424,774,879 is 40289182992.
