Given numbers are 357,556,786,693
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 357,556,786,693 is 858080916.
Find LCM of 357,556,786,693 with Prime Factorization
| 2 | 357, 556, 786, 693 |
| 3 | 357, 278, 393, 693 |
| 7 | 119, 278, 131, 231 |
| 17, 278, 131, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 278 x 131 x 33 = 858080916
Therefore, the lowest common multiple of 357,556,786,693 is 858080916.
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.
357 x 556 x 786 x 693 = 108118195416
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
556 : 1, 2, 4, 139, 278, 556
786 : 1, 2, 3, 6, 131, 262, 393, 786
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,556,786,693, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
556:2x 2x 139
786:2x 3x 131
693:3x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 108118195416/(1x126)
LCM = 108118195416/126
LCM = 858080916
Thus, we can understand that the LCM of 357,556,786,693 is 858080916.
