Given numbers are 815,421,174,834,912
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,421,174,834,912 is 1261384067280.
Find LCM of 815,421,174,834,912 with Prime Factorization
| 2 | 815, 421, 174, 834, 912 |
| 3 | 815, 421, 87, 417, 456 |
| 815, 421, 29, 139, 152 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 815 x 421 x 29 x 139 x 152 = 1261384067280
Therefore, the lowest common multiple of 815,421,174,834,912 is 1261384067280.
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.
815 x 421 x 174 x 834 x 912 = 45409826422080
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.
815 : 1, 5, 163, 815
421 : 1, 421
174 : 1, 2, 3, 6, 29, 58, 87, 174
834 : 1, 2, 3, 6, 139, 278, 417, 834
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,421,174,834,912, is 1.
Now, the common factors can be found like this.
815:5x 163
421:421
174:2x 3x 29
834:2x 3x 139
912:2x 2x 2x 2x 3x 19
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 45409826422080/(1x36)
LCM = 45409826422080/36
LCM = 1261384067280
Thus, we can understand that the LCM of 815,421,174,834,912 is 1261384067280.
