Given numbers are 375,785,343,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 375,785,343,691 is 13954140375.
Find LCM of 375,785,343,691 with Prime Factorization
| 5 | 375, 785, 343, 691 |
| 75, 157, 343, 691 |
Multiply the prime numbers at the bottom and the left side.
5 x 75 x 157 x 343 x 691 = 13954140375
Therefore, the lowest common multiple of 375,785,343,691 is 13954140375.
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.
375 x 785 x 343 x 691 = 69770701875
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.
375 : 1, 3, 5, 15, 25, 75, 125, 375
785 : 1, 5, 157, 785
343 : 1, 7, 49, 343
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 375,785,343,691, is 1.
Now, the common factors can be found like this.
375:3x 5x 5x 5
785:5x 157
343:7x 7x 7
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 69770701875/(1x5)
LCM = 69770701875/5
LCM = 13954140375
Thus, we can understand that the LCM of 375,785,343,691 is 13954140375.
