Given numbers are 371,668,689,188
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 371,668,689,188 is 151422908.
Find LCM of 371,668,689,188 with Prime Factorization
| 2 | 371, 668, 689, 188 |
| 2 | 371, 334, 689, 94 |
| 53 | 371, 167, 689, 47 |
| 7, 167, 13, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 53 x 7 x 167 x 13 x 47 = 151422908
Therefore, the lowest common multiple of 371,668,689,188 is 151422908.
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.
371 x 668 x 689 x 188 = 32101656496
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.
371 : 1, 7, 53, 371
668 : 1, 2, 4, 167, 334, 668
689 : 1, 13, 53, 689
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 371,668,689,188, is 1.
Now, the common factors can be found like this.
371:7x 53
668:2x 2x 167
689:13x 53
188:2x 2x 47
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 53 = 212
Therefore, the value for common factors is 212.
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 = 32101656496/(1x212)
LCM = 32101656496/212
LCM = 151422908
Thus, we can understand that the LCM of 371,668,689,188 is 151422908.
