The LCM of 985,114,472,728,742 is 127811622120.
Find LCM of 985,114,472,728,742 with Prime Factorization
| 2 | 985, 114, 472, 728, 742 |
| 2 | 985, 57, 236, 364, 371 |
| 2 | 985, 57, 118, 182, 371 |
| 7 | 985, 57, 59, 91, 371 |
| 985, 57, 59, 13, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 985 x 57 x 59 x 13 x 53 = 127811622120
Therefore, the lowest common multiple of 985,114,472,728,742 is 127811622120.
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.
985 x 114 x 472 x 728 x 742 = 28629803354880
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.
985 : 1, 5, 197, 985
114 : 1, 2, 3, 6, 19, 38, 57, 114
472 : 1, 2, 4, 8, 59, 118, 236, 472
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,114,472,728,742, is 1.
Now, the common factors can be found like this.
985:5x 197
114:2x 3x 19
472:2x 2x 2x 59
728:2x 2x 2x 7x 13
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 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 28629803354880/(1x224)
LCM = 28629803354880/224
LCM = 127811622120
Thus, we can understand that the LCM of 985,114,472,728,742 is 127811622120.
