Find LCM of 993,752,752,781 with Prime Factorization
| 2 | 993, 752, 752, 781 |
| 2 | 993, 376, 376, 781 |
| 2 | 993, 188, 188, 781 |
| 2 | 993, 94, 94, 781 |
| 47 | 993, 47, 47, 781 |
| 993, 1, 1, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 47 x 993 x 1 x 1 x 781 = 583200816
Therefore, the lowest common multiple of 993,752,752,781 is 583200816.
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.
993 x 752 x 752 x 781 = 438567013632
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.
993 : 1, 3, 331, 993
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,752,752,781, is 1.
Now, the common factors can be found like this.
993:3x 331
752:2x 2x 2x 2x 47
752:2x 2x 2x 2x 47
781:11x 71
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 47 = 752
Therefore, the value for common factors is 752.
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 = 438567013632/(1x752)
LCM = 438567013632/752
LCM = 583200816
Thus, we can understand that the LCM of 993,752,752,781 is 583200816.
