Given numbers are 361,209,182,461,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,209,182,461,840 is 19990490520.
Find LCM of 361,209,182,461,840 with Prime Factorization
| 2 | 361, 209, 182, 461, 840 |
| 7 | 361, 209, 91, 461, 420 |
| 19 | 361, 209, 13, 461, 60 |
| 19, 11, 13, 461, 60 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 19 x 11 x 13 x 461 x 60 = 19990490520
Therefore, the lowest common multiple of 361,209,182,461,840 is 19990490520.
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.
361 x 209 x 182 x 461 x 840 = 5317470478320
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.
361 : 1, 19, 361
209 : 1, 11, 19, 209
182 : 1, 2, 7, 13, 14, 26, 91, 182
461 : 1, 461
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 361,209,182,461,840, is 1.
Now, the common factors can be found like this.
361:19x 19
209:11x 19
182:2x 7x 13
461:461
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 7x 19 = 266
Therefore, the value for common factors is 266.
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 = 5317470478320/(1x266)
LCM = 5317470478320/266
LCM = 19990490520
Thus, we can understand that the LCM of 361,209,182,461,840 is 19990490520.
