Given numbers are 199,630,840,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 199,630,840,197 is 98791560.
Find LCM of 199,630,840,197 with Prime Factorization
| 2 | 199, 630, 840, 197 |
| 3 | 199, 315, 420, 197 |
| 5 | 199, 105, 140, 197 |
| 7 | 199, 21, 28, 197 |
| 199, 3, 4, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 199 x 3 x 4 x 197 = 98791560
Therefore, the lowest common multiple of 199,630,840,197 is 98791560.
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 630 x 840 x 197 = 20746227600
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
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
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
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,630,840,197, is 1.
Now, the common factors can be found like this.
199:199
630:2x 3x 3x 5x 7
840:2x 2x 2x 3x 5x 7
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 20746227600/(1x210)
LCM = 20746227600/210
LCM = 98791560
Thus, we can understand that the LCM of 199,630,840,197 is 98791560.
