Given numbers are 364,947,455,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 364,947,455,663 is 87900540.
Find LCM of 364,947,455,663 with Prime Factorization
| 7 | 364, 947, 455, 663 |
| 13 | 52, 947, 65, 663 |
| 4, 947, 5, 51 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 4 x 947 x 5 x 51 = 87900540
Therefore, the lowest common multiple of 364,947,455,663 is 87900540.
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.
364 x 947 x 455 x 663 = 103986338820
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.
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
947 : 1, 947
455 : 1, 5, 7, 13, 35, 65, 91, 455
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 364,947,455,663, is 1.
Now, the common factors can be found like this.
364:2x 2x 7x 13
947:947
455:5x 7x 13
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 13x 13 = 1183
Therefore, the value for common factors is 1183.
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 = 103986338820/(1x1183)
LCM = 103986338820/1183
LCM = 87900540
Thus, we can understand that the LCM of 364,947,455,663 is 87900540.
