Given numbers are 978,437,912,931,949
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,437,912,931,949 is 158991011088.
Find LCM of 978,437,912,931,949 with Prime Factorization
| 2 | 978, 437, 912, 931, 949 |
| 3 | 489, 437, 456, 931, 949 |
| 19 | 163, 437, 152, 931, 949 |
| 163, 23, 8, 49, 949 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 163 x 23 x 8 x 49 x 949 = 158991011088
Therefore, the lowest common multiple of 978,437,912,931,949 is 158991011088.
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.
978 x 437 x 912 x 931 x 949 = 344374530016608
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
437 : 1, 19, 23, 437
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
931 : 1, 7, 19, 49, 133, 931
949 : 1, 13, 73, 949
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,437,912,931,949, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
437:19x 23
912:2x 2x 2x 2x 3x 19
931:7x 7x 19
949:13x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19x 19 = 2166
Therefore, the value for common factors is 2166.
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 = 344374530016608/(1x2166)
LCM = 344374530016608/2166
LCM = 158991011088
Thus, we can understand that the LCM of 978,437,912,931,949 is 158991011088.
