Given numbers are 355,685,742,552,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 355,685,742,552,938 is 667323947640.
Find LCM of 355,685,742,552,938 with Prime Factorization
| 2 | 355, 685, 742, 552, 938 |
| 5 | 355, 685, 371, 276, 469 |
| 7 | 71, 137, 371, 276, 469 |
| 71, 137, 53, 276, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 71 x 137 x 53 x 276 x 67 = 667323947640
Therefore, the lowest common multiple of 355,685,742,552,938 is 667323947640.
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.
355 x 685 x 742 x 552 x 938 = 93425352669600
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.
355 : 1, 5, 71, 355
685 : 1, 5, 137, 685
742 : 1, 2, 7, 14, 53, 106, 371, 742
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,685,742,552,938, is 1.
Now, the common factors can be found like this.
355:5x 71
685:5x 137
742:2x 7x 53
552:2x 2x 2x 3x 23
938:2x 7x 67
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 93425352669600/(1x140)
LCM = 93425352669600/140
LCM = 667323947640
Thus, we can understand that the LCM of 355,685,742,552,938 is 667323947640.
