Given numbers are 749,817,818,458,228
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,817,818,458,228 is 687771080556.
Find LCM of 749,817,818,458,228 with Prime Factorization
| 2 | 749, 817, 818, 458, 228 |
| 19 | 749, 817, 409, 229, 114 |
| 749, 43, 409, 229, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 749 x 43 x 409 x 229 x 6 = 687771080556
Therefore, the lowest common multiple of 749,817,818,458,228 is 687771080556.
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.
749 x 817 x 818 x 458 x 228 = 52270602122256
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.
749 : 1, 7, 107, 749
817 : 1, 19, 43, 817
818 : 1, 2, 409, 818
458 : 1, 2, 229, 458
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,817,818,458,228, is 1.
Now, the common factors can be found like this.
749:7x 107
817:19x 43
818:2x 409
458:2x 229
228:2x 2x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 19 = 76
Therefore, the value for common factors is 76.
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 = 52270602122256/(1x76)
LCM = 52270602122256/76
LCM = 687771080556
Thus, we can understand that the LCM of 749,817,818,458,228 is 687771080556.
