Given numbers are 961,481,494,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 961,481,494,987 is 17336810946.
Find LCM of 961,481,494,987 with Prime Factorization
13 | 961, 481, 494, 987 |
961, 37, 38, 987 |
Multiply the prime numbers at the bottom and the left side.
13 x 961 x 37 x 38 x 987 = 17336810946
Therefore, the lowest common multiple of 961,481,494,987 is 17336810946.
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.
961 x 481 x 494 x 987 = 225378542298
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.
961 : 1, 31, 961
481 : 1, 13, 37, 481
494 : 1, 2, 13, 19, 26, 38, 247, 494
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,481,494,987, is 1.
Now, the common factors can be found like this.
961:31x 31
481:13x 37
494:2x 13x 19
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 225378542298/(1x13)
LCM = 225378542298/13
LCM = 17336810946
Thus, we can understand that the LCM of 961,481,494,987 is 17336810946.
