Find LCM of 776,188,749,720,831 with Prime Factorization
| 2 | 776, 188, 749, 720, 831 |
| 2 | 388, 94, 749, 360, 831 |
| 2 | 194, 47, 749, 180, 831 |
| 3 | 97, 47, 749, 90, 831 |
| 97, 47, 749, 30, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 97 x 47 x 749 x 30 x 277 = 681025973040
Therefore, the lowest common multiple of 776,188,749,720,831 is 681025973040.
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.
776 x 188 x 749 x 720 x 831 = 65378493411840
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.
776 : 1, 2, 4, 8, 97, 194, 388, 776
188 : 1, 2, 4, 47, 94, 188
749 : 1, 7, 107, 749
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 776,188,749,720,831, is 1.
Now, the common factors can be found like this.
776:2x 2x 2x 97
188:2x 2x 47
749:7x 107
720:2x 2x 2x 2x 3x 3x 5
831:3x 277
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 2x 3 = 96
Therefore, the value for common factors is 96.
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 = 65378493411840/(1x96)
LCM = 65378493411840/96
LCM = 681025973040
Thus, we can understand that the LCM of 776,188,749,720,831 is 681025973040.
