Given numbers are 126,921,748,804
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,921,748,804 is 969293556.
Find LCM of 126,921,748,804 with Prime Factorization
| 2 | 126, 921, 748, 804 |
| 2 | 63, 921, 374, 402 |
| 3 | 63, 921, 187, 201 |
| 21, 307, 187, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 21 x 307 x 187 x 67 = 969293556
Therefore, the lowest common multiple of 126,921,748,804 is 969293556.
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 921 x 748 x 804 = 69789136032
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
921 : 1, 3, 307, 921
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,921,748,804, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
921:3x 307
748:2x 2x 11x 17
804:2x 2x 3x 67
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 3 = 72
Therefore, the value for common factors is 72.
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 = 69789136032/(1x72)
LCM = 69789136032/72
LCM = 969293556
Thus, we can understand that the LCM of 126,921,748,804 is 969293556.
