Given numbers are 126,529,851,742,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,529,851,742,644 is 261416988.
Find LCM of 126,529,851,742,644 with Prime Factorization
| 2 | 126, 529, 851, 742, 644 |
| 7 | 63, 529, 851, 371, 322 |
| 23 | 9, 529, 851, 53, 46 |
| 9, 23, 37, 53, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 9 x 23 x 37 x 53 x 2 = 261416988
Therefore, the lowest common multiple of 126,529,851,742,644 is 261416988.
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.
126 x 529 x 851 x 742 x 644 = 27104758983792
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
529 : 1, 23, 529
851 : 1, 23, 37, 851
742 : 1, 2, 7, 14, 53, 106, 371, 742
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,529,851,742,644, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
529:23x 23
851:23x 37
742:2x 7x 53
644:2x 2x 7x 23
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 7x 7x 23x 23 = 103684
Therefore, the value for common factors is 103684.
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 = 27104758983792/(1x103684)
LCM = 27104758983792/103684
LCM = 261416988
Thus, we can understand that the LCM of 126,529,851,742,644 is 261416988.
