Given numbers are 219,992,399,931,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 219,992,399,931,380 is 1011289440.
Find LCM of 219,992,399,931,380 with Prime Factorization
| 2 | 219, 992, 399, 931, 380 |
| 2 | 219, 496, 399, 931, 190 |
| 3 | 219, 248, 399, 931, 95 |
| 7 | 73, 248, 133, 931, 95 |
| 19 | 73, 248, 19, 133, 95 |
| 73, 248, 1, 7, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 19 x 73 x 248 x 1 x 7 x 5 = 1011289440
Therefore, the lowest common multiple of 219,992,399,931,380 is 1011289440.
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.
219 x 992 x 399 x 931 x 380 = 30666340978560
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.
219 : 1, 3, 73, 219
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
399 : 1, 3, 7, 19, 21, 57, 133, 399
931 : 1, 7, 19, 49, 133, 931
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 219,992,399,931,380, is 1.
Now, the common factors can be found like this.
219:3x 73
992:2x 2x 2x 2x 2x 31
399:3x 7x 19
931:7x 7x 19
380:2x 2x 5x 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 7x 19x 19 = 30324
Therefore, the value for common factors is 30324.
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 = 30666340978560/(1x30324)
LCM = 30666340978560/30324
LCM = 1011289440
Thus, we can understand that the LCM of 219,992,399,931,380 is 1011289440.
