Given numbers are 920,989,729,169,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,989,729,169,788 is 960144817320.
Find LCM of 920,989,729,169,788 with Prime Factorization
| 2 | 920, 989, 729, 169, 788 |
| 2 | 460, 989, 729, 169, 394 |
| 23 | 230, 989, 729, 169, 197 |
| 10, 43, 729, 169, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 10 x 43 x 729 x 169 x 197 = 960144817320
Therefore, the lowest common multiple of 920,989,729,169,788 is 960144817320.
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.
920 x 989 x 729 x 169 x 788 = 88333323193440
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
989 : 1, 23, 43, 989
729 : 1, 3, 9, 27, 81, 243, 729
169 : 1, 13, 169
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,989,729,169,788, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
989:23x 43
729:3x 3x 3x 3x 3x 3
169:13x 13
788:2x 2x 197
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 23 = 92
Therefore, the value for common factors is 92.
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 = 88333323193440/(1x92)
LCM = 88333323193440/92
LCM = 960144817320
Thus, we can understand that the LCM of 920,989,729,169,788 is 960144817320.
