Given numbers are 652,949,390,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 652,949,390,438 is 9281220.
Find LCM of 652,949,390,438 with Prime Factorization
| 2 | 652, 949, 390, 438 |
| 3 | 326, 949, 195, 219 |
| 13 | 326, 949, 65, 73 |
| 73 | 326, 73, 5, 73 |
| 326, 1, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 73 x 326 x 1 x 5 x 1 = 9281220
Therefore, the lowest common multiple of 652,949,390,438 is 9281220.
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.
652 x 949 x 390 x 438 = 105694533360
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.
652 : 1, 2, 4, 163, 326, 652
949 : 1, 13, 73, 949
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 652,949,390,438, is 1.
Now, the common factors can be found like this.
652:2x 2x 163
949:13x 73
390:2x 3x 5x 13
438:2x 3x 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 2x 3x 13x 73 = 11388
Therefore, the value for common factors is 11388.
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 = 105694533360/(1x11388)
LCM = 105694533360/11388
LCM = 9281220
Thus, we can understand that the LCM of 652,949,390,438 is 9281220.
