Given numbers are 946,942,411,838,972
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,942,411,838,972 is 4143445665876.
Find LCM of 946,942,411,838,972 with Prime Factorization
| 2 | 946, 942, 411, 838, 972 |
| 3 | 473, 471, 411, 419, 486 |
| 473, 157, 137, 419, 162 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 473 x 157 x 137 x 419 x 162 = 4143445665876
Therefore, the lowest common multiple of 946,942,411,838,972 is 4143445665876.
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.
946 x 942 x 411 x 838 x 972 = 298328087943072
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
942 : 1, 2, 3, 6, 157, 314, 471, 942
411 : 1, 3, 137, 411
838 : 1, 2, 419, 838
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,942,411,838,972, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
942:2x 3x 157
411:3x 137
838:2x 419
972:2x 2x 3x 3x 3x 3x 3
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 = 298328087943072/(1x72)
LCM = 298328087943072/72
LCM = 4143445665876
Thus, we can understand that the LCM of 946,942,411,838,972 is 4143445665876.
