Given numbers are 645,976,741,932,472
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 645,976,741,932,472 is 2137540825680.
Find LCM of 645,976,741,932,472 with Prime Factorization
| 2 | 645, 976, 741, 932, 472 |
| 2 | 645, 488, 741, 466, 236 |
| 2 | 645, 244, 741, 233, 118 |
| 3 | 645, 122, 741, 233, 59 |
| 215, 122, 247, 233, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 215 x 122 x 247 x 233 x 59 = 2137540825680
Therefore, the lowest common multiple of 645,976,741,932,472 is 2137540825680.
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.
645 x 976 x 741 x 932 x 472 = 205203919265280
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
741 : 1, 3, 13, 19, 39, 57, 247, 741
932 : 1, 2, 4, 233, 466, 932
472 : 1, 2, 4, 8, 59, 118, 236, 472
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,976,741,932,472, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
976:2x 2x 2x 2x 61
741:3x 13x 19
932:2x 2x 233
472:2x 2x 2x 59
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 3 = 96
Therefore, the value for common factors is 96.
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 = 205203919265280/(1x96)
LCM = 205203919265280/96
LCM = 2137540825680
Thus, we can understand that the LCM of 645,976,741,932,472 is 2137540825680.
