Given numbers are 619,672,813,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,672,813,756 is 1014545952.
Find LCM of 619,672,813,756 with Prime Factorization
| 2 | 619, 672, 813, 756 |
| 2 | 619, 336, 813, 378 |
| 3 | 619, 168, 813, 189 |
| 7 | 619, 56, 271, 63 |
| 619, 8, 271, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 619 x 8 x 271 x 9 = 1014545952
Therefore, the lowest common multiple of 619,672,813,756 is 1014545952.
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.
619 x 672 x 813 x 756 = 255665579904
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.
619 : 1, 619
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
813 : 1, 3, 271, 813
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,672,813,756, is 1.
Now, the common factors can be found like this.
619:619
672:2x 2x 2x 2x 2x 3x 7
813:3x 271
756:2x 2x 3x 3x 3x 7
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 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 255665579904/(1x252)
LCM = 255665579904/252
LCM = 1014545952
Thus, we can understand that the LCM of 619,672,813,756 is 1014545952.
