Given numbers are 874,574,667,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,574,667,690 is 109114530.
Find LCM of 874,574,667,690 with Prime Factorization
| 2 | 874, 574, 667, 690 |
| 23 | 437, 287, 667, 345 |
| 19, 287, 29, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 19 x 287 x 29 x 15 = 109114530
Therefore, the lowest common multiple of 874,574,667,690 is 109114530.
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.
874 x 574 x 667 x 690 = 230886345480
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
574 : 1, 2, 7, 14, 41, 82, 287, 574
667 : 1, 23, 29, 667
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,574,667,690, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
574:2x 7x 41
667:23x 29
690:2x 3x 5x 23
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 23x 23 = 2116
Therefore, the value for common factors is 2116.
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 = 230886345480/(1x2116)
LCM = 230886345480/2116
LCM = 109114530
Thus, we can understand that the LCM of 874,574,667,690 is 109114530.
