Given numbers are 451,715,636,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,715,636,989 is 18439252260.
Find LCM of 451,715,636,989 with Prime Factorization
11 | 451, 715, 636, 989 |
41, 65, 636, 989 |
Multiply the prime numbers at the bottom and the left side.
11 x 41 x 65 x 636 x 989 = 18439252260
Therefore, the lowest common multiple of 451,715,636,989 is 18439252260.
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.
451 x 715 x 636 x 989 = 202831774860
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.
451 : 1, 11, 41, 451
715 : 1, 5, 11, 13, 55, 65, 143, 715
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,715,636,989, is 1.
Now, the common factors can be found like this.
451:11x 41
715:5x 11x 13
636:2x 2x 3x 53
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.
11 = 11
Therefore, the value for common factors is 11.
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 = 202831774860/(1x11)
LCM = 202831774860/11
LCM = 18439252260
Thus, we can understand that the LCM of 451,715,636,989 is 18439252260.
