Given numbers are 253,363,420,247,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,363,420,247,403 is 8949961020.
Find LCM of 253,363,420,247,403 with Prime Factorization
| 3 | 253, 363, 420, 247, 403 |
| 11 | 253, 121, 140, 247, 403 |
| 13 | 23, 11, 140, 247, 403 |
| 23, 11, 140, 19, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 23 x 11 x 140 x 19 x 31 = 8949961020
Therefore, the lowest common multiple of 253,363,420,247,403 is 8949961020.
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.
253 x 363 x 420 x 247 x 403 = 3839533277580
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.
253 : 1, 11, 23, 253
363 : 1, 3, 11, 33, 121, 363
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
247 : 1, 13, 19, 247
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,363,420,247,403, is 1.
Now, the common factors can be found like this.
253:11x 23
363:3x 11x 11
420:2x 2x 3x 5x 7
247:13x 19
403:13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 13 = 429
Therefore, the value for common factors is 429.
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 = 3839533277580/(1x429)
LCM = 3839533277580/429
LCM = 8949961020
Thus, we can understand that the LCM of 253,363,420,247,403 is 8949961020.
