Given numbers are 494,187,199,420,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 494,187,199,420,393 is 505722437220.
Find LCM of 494,187,199,420,393 with Prime Factorization
| 2 | 494, 187, 199, 420, 393 |
| 3 | 247, 187, 199, 210, 393 |
| 247, 187, 199, 70, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 247 x 187 x 199 x 70 x 131 = 505722437220
Therefore, the lowest common multiple of 494,187,199,420,393 is 505722437220.
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.
494 x 187 x 199 x 420 x 393 = 3034334623320
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.
494 : 1, 2, 13, 19, 26, 38, 247, 494
187 : 1, 11, 17, 187
199 : 1, 199
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,187,199,420,393, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
187:11x 17
199:199
420:2x 2x 3x 5x 7
393:3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 3034334623320/(1x6)
LCM = 3034334623320/6
LCM = 505722437220
Thus, we can understand that the LCM of 494,187,199,420,393 is 505722437220.
