Given numbers are 788,870,524,622,122
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,870,524,622,122 is 851877198780.
Find LCM of 788,870,524,622,122 with Prime Factorization
| 2 | 788, 870, 524, 622, 122 |
| 2 | 394, 435, 262, 311, 61 |
| 197, 435, 131, 311, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 197 x 435 x 131 x 311 x 61 = 851877198780
Therefore, the lowest common multiple of 788,870,524,622,122 is 851877198780.
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.
788 x 870 x 524 x 622 x 122 = 27260070360960
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.
788 : 1, 2, 4, 197, 394, 788
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
524 : 1, 2, 4, 131, 262, 524
622 : 1, 2, 311, 622
122 : 1, 2, 61, 122
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,870,524,622,122, is 2.
Now, the common factors can be found like this.
788:2x 2x 197
870:2x 3x 5x 29
524:2x 2x 131
622:2x 311
122:2x 61
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 2 = 16
Therefore, the value for common factors is 16.
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 = 27260070360960/(2x16)
LCM = 27260070360960/32
LCM = 851877198780
Thus, we can understand that the LCM of 788,870,524,622,122 is 851877198780.
