Given numbers are 787,822,128,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,822,128,762 is 5258116992.
Find LCM of 787,822,128,762 with Prime Factorization
| 2 | 787, 822, 128, 762 |
| 3 | 787, 411, 64, 381 |
| 787, 137, 64, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 787 x 137 x 64 x 127 = 5258116992
Therefore, the lowest common multiple of 787,822,128,762 is 5258116992.
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.
787 x 822 x 128 x 762 = 63097403904
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.
787 : 1, 787
822 : 1, 2, 3, 6, 137, 274, 411, 822
128 : 1, 2, 4, 8, 16, 32, 64, 128
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,822,128,762, is 1.
Now, the common factors can be found like this.
787:787
822:2x 3x 137
128:2x 2x 2x 2x 2x 2x 2
762:2x 3x 127
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 3 = 12
Therefore, the value for common factors is 12.
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 = 63097403904/(1x12)
LCM = 63097403904/12
LCM = 5258116992
Thus, we can understand that the LCM of 787,822,128,762 is 5258116992.
