Given numbers are 743,749,788,985
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,749,788,985 is 2192637580.
Find LCM of 743,749,788,985 with Prime Factorization
197 | 743, 749, 788, 985 |
743, 749, 4, 5 |
Multiply the prime numbers at the bottom and the left side.
197 x 743 x 749 x 4 x 5 = 2192637580
Therefore, the lowest common multiple of 743,749,788,985 is 2192637580.
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.
743 x 749 x 788 x 985 = 431949603260
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.
743 : 1, 743
749 : 1, 7, 107, 749
788 : 1, 2, 4, 197, 394, 788
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,749,788,985, is 1.
Now, the common factors can be found like this.
743:743
749:7x 107
788:2x 2x 197
985:5x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
197 = 197
Therefore, the value for common factors is 197.
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 = 431949603260/(1x197)
LCM = 431949603260/197
LCM = 2192637580
Thus, we can understand that the LCM of 743,749,788,985 is 2192637580.
