Given numbers are 189,742,842,716,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,742,842,716,992 is 748832134176.
Find LCM of 189,742,842,716,992 with Prime Factorization
| 2 | 189, 742, 842, 716, 992 |
| 2 | 189, 371, 421, 358, 496 |
| 7 | 189, 371, 421, 179, 248 |
| 27, 53, 421, 179, 248 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 27 x 53 x 421 x 179 x 248 = 748832134176
Therefore, the lowest common multiple of 189,742,842,716,992 is 748832134176.
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.
189 x 742 x 842 x 716 x 992 = 83869199027712
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
742 : 1, 2, 7, 14, 53, 106, 371, 742
842 : 1, 2, 421, 842
716 : 1, 2, 4, 179, 358, 716
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,742,842,716,992, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
742:2x 7x 53
842:2x 421
716:2x 2x 179
992:2x 2x 2x 2x 2x 31
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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 83869199027712/(1x112)
LCM = 83869199027712/112
LCM = 748832134176
Thus, we can understand that the LCM of 189,742,842,716,992 is 748832134176.
