Find LCM of 778,648,342,387,892 with Prime Factorization
| 2 | 778, 648, 342, 387, 892 |
| 2 | 389, 324, 171, 387, 446 |
| 3 | 389, 162, 171, 387, 223 |
| 3 | 389, 54, 57, 129, 223 |
| 389, 18, 19, 43, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 389 x 18 x 19 x 43 x 223 = 45925249752
Therefore, the lowest common multiple of 778,648,342,387,892 is 45925249752.
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.
778 x 648 x 342 x 387 x 892 = 59519123678592
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.
778 : 1, 2, 389, 778
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
387 : 1, 3, 9, 43, 129, 387
892 : 1, 2, 4, 223, 446, 892
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,648,342,387,892, is 1.
Now, the common factors can be found like this.
778:2x 389
648:2x 2x 2x 3x 3x 3x 3
342:2x 3x 3x 19
387:3x 3x 43
892:2x 2x 223
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 3x 3x 3 = 1296
Therefore, the value for common factors is 1296.
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 = 59519123678592/(1x1296)
LCM = 59519123678592/1296
LCM = 45925249752
Thus, we can understand that the LCM of 778,648,342,387,892 is 45925249752.
