Given numbers are 553,871,642,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 553,871,642,642 is 309227646.
Find LCM of 553,871,642,642 with Prime Factorization
2 | 553, 871, 642, 642 |
3 | 553, 871, 321, 321 |
107 | 553, 871, 107, 107 |
553, 871, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 553 x 871 x 1 x 1 = 309227646
Therefore, the lowest common multiple of 553,871,642,642 is 309227646.
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.
553 x 871 x 642 x 642 = 198524148732
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.
553 : 1, 7, 79, 553
871 : 1, 13, 67, 871
642 : 1, 2, 3, 6, 107, 214, 321, 642
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,871,642,642, is 1.
Now, the common factors can be found like this.
553:7x 79
871:13x 67
642:2x 3x 107
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 107 = 642
Therefore, the value for common factors is 642.
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 = 198524148732/(1x642)
LCM = 198524148732/642
LCM = 309227646
Thus, we can understand that the LCM of 553,871,642,642 is 309227646.
