Given numbers are 852,965,702,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 852,965,702,640 is 3078241920.
Find LCM of 852,965,702,640 with Prime Factorization
| 2 | 852, 965, 702, 640 |
| 2 | 426, 965, 351, 320 |
| 3 | 213, 965, 351, 160 |
| 5 | 71, 965, 117, 160 |
| 71, 193, 117, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 71 x 193 x 117 x 32 = 3078241920
Therefore, the lowest common multiple of 852,965,702,640 is 3078241920.
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.
852 x 965 x 702 x 640 = 369389030400
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.
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
965 : 1, 5, 193, 965
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 852,965,702,640, is 1.
Now, the common factors can be found like this.
852:2x 2x 3x 71
965:5x 193
702:2x 3x 3x 3x 13
640:2x 2x 2x 2x 2x 2x 2x 5
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 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 369389030400/(1x120)
LCM = 369389030400/120
LCM = 3078241920
Thus, we can understand that the LCM of 852,965,702,640 is 3078241920.
