Given numbers are 851,351,563,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,351,563,989 is 7231252509.
Find LCM of 851,351,563,989 with Prime Factorization
| 23 | 851, 351, 563, 989 |
| 37, 351, 563, 43 |
Multiply the prime numbers at the bottom and the left side.
23 x 37 x 351 x 563 x 43 = 7231252509
Therefore, the lowest common multiple of 851,351,563,989 is 7231252509.
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.
851 x 351 x 563 x 989 = 166318807707
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.
851 : 1, 23, 37, 851
351 : 1, 3, 9, 13, 27, 39, 117, 351
563 : 1, 563
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,351,563,989, is 1.
Now, the common factors can be found like this.
851:23x 37
351:3x 3x 3x 13
563:563
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 166318807707/(1x23)
LCM = 166318807707/23
LCM = 7231252509
Thus, we can understand that the LCM of 851,351,563,989 is 7231252509.
