Given numbers are 451,165,121,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,165,121,988 is 73522020.
Find LCM of 451,165,121,988 with Prime Factorization
11 | 451, 165, 121, 988 |
41, 15, 11, 988 |
Multiply the prime numbers at the bottom and the left side.
11 x 41 x 15 x 11 x 988 = 73522020
Therefore, the lowest common multiple of 451,165,121,988 is 73522020.
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 165 x 121 x 988 = 8896164420
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
165 : 1, 3, 5, 11, 15, 33, 55, 165
121 : 1, 11, 121
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,165,121,988, is 1.
Now, the common factors can be found like this.
451:11x 41
165:3x 5x 11
121:11x 11
988:2x 2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 8896164420/(1x121)
LCM = 8896164420/121
LCM = 73522020
Thus, we can understand that the LCM of 451,165,121,988 is 73522020.
