Given numbers are 657,830,458,556,558
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,830,458,556,558 is 1076181281820.
Find LCM of 657,830,458,556,558 with Prime Factorization
| 2 | 657, 830, 458, 556, 558 |
| 3 | 657, 415, 229, 278, 279 |
| 3 | 219, 415, 229, 278, 93 |
| 73, 415, 229, 278, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 73 x 415 x 229 x 278 x 31 = 1076181281820
Therefore, the lowest common multiple of 657,830,458,556,558 is 1076181281820.
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.
657 x 830 x 458 x 556 x 558 = 77485052291040
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.
657 : 1, 3, 9, 73, 219, 657
830 : 1, 2, 5, 10, 83, 166, 415, 830
458 : 1, 2, 229, 458
556 : 1, 2, 4, 139, 278, 556
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,830,458,556,558, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
830:2x 5x 83
458:2x 229
556:2x 2x 139
558:2x 3x 3x 31
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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 77485052291040/(1x72)
LCM = 77485052291040/72
LCM = 1076181281820
Thus, we can understand that the LCM of 657,830,458,556,558 is 1076181281820.
