Given numbers are 199,680,892,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 199,680,892,840 is 633703560.
Find LCM of 199,680,892,840 with Prime Factorization
| 2 | 199, 680, 892, 840 |
| 2 | 199, 340, 446, 420 |
| 2 | 199, 170, 223, 210 |
| 5 | 199, 85, 223, 105 |
| 199, 17, 223, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 199 x 17 x 223 x 21 = 633703560
Therefore, the lowest common multiple of 199,680,892,840 is 633703560.
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.
199 x 680 x 892 x 840 = 101392569600
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.
199 : 1, 199
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
892 : 1, 2, 4, 223, 446, 892
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,680,892,840, is 1.
Now, the common factors can be found like this.
199:199
680:2x 2x 2x 5x 17
892:2x 2x 223
840:2x 2x 2x 3x 5x 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 2x 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 101392569600/(1x160)
LCM = 101392569600/160
LCM = 633703560
Thus, we can understand that the LCM of 199,680,892,840 is 633703560.
