Given numbers are 963,985,305,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 963,985,305,749 is 405032985.
Find LCM of 963,985,305,749 with Prime Factorization
5 | 963, 985, 305, 749 |
107 | 963, 197, 61, 749 |
9, 197, 61, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 107 x 9 x 197 x 61 x 7 = 405032985
Therefore, the lowest common multiple of 963,985,305,749 is 405032985.
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.
963 x 985 x 305 x 749 = 216692646975
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.
963 : 1, 3, 9, 107, 321, 963
985 : 1, 5, 197, 985
305 : 1, 5, 61, 305
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 963,985,305,749, is 1.
Now, the common factors can be found like this.
963:3x 3x 107
985:5x 197
305:5x 61
749:7x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 107 = 535
Therefore, the value for common factors is 535.
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 = 216692646975/(1x535)
LCM = 216692646975/535
LCM = 405032985
Thus, we can understand that the LCM of 963,985,305,749 is 405032985.
