Given numbers are 120,636,538,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 120,636,538,742 is 11975880.
Find LCM of 120,636,538,742 with Prime Factorization
2 | 120, 636, 538, 742 |
2 | 60, 318, 269, 371 |
3 | 30, 159, 269, 371 |
53 | 10, 53, 269, 371 |
10, 1, 269, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 53 x 10 x 1 x 269 x 7 = 11975880
Therefore, the lowest common multiple of 120,636,538,742 is 11975880.
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.
120 x 636 x 538 x 742 = 30466638720
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.
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
538 : 1, 2, 269, 538
742 : 1, 2, 7, 14, 53, 106, 371, 742
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,636,538,742, is 2.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
636:2x 2x 3x 53
538:2x 269
742:2x 7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 53 = 1272
Therefore, the value for common factors is 1272.
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 = 30466638720/(2x1272)
LCM = 30466638720/2544
LCM = 11975880
Thus, we can understand that the LCM of 120,636,538,742 is 11975880.
