Given numbers are 228,817,403,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 228,817,403,615 is 809957460.
Find LCM of 228,817,403,615 with Prime Factorization
| 3 | 228, 817, 403, 615 |
| 19 | 76, 817, 403, 205 |
| 4, 43, 403, 205 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 4 x 43 x 403 x 205 = 809957460
Therefore, the lowest common multiple of 228,817,403,615 is 809957460.
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.
228 x 817 x 403 x 615 = 46167575220
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
817 : 1, 19, 43, 817
403 : 1, 13, 31, 403
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,817,403,615, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
817:19x 43
403:13x 31
615:3x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19 = 57
Therefore, the value for common factors is 57.
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 = 46167575220/(1x57)
LCM = 46167575220/57
LCM = 809957460
Thus, we can understand that the LCM of 228,817,403,615 is 809957460.
