Given numbers are 379,172,645,941
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 379,172,645,941 is 920128620.
Find LCM of 379,172,645,941 with Prime Factorization
43 | 379, 172, 645, 941 |
379, 4, 15, 941 |
Multiply the prime numbers at the bottom and the left side.
43 x 379 x 4 x 15 x 941 = 920128620
Therefore, the lowest common multiple of 379,172,645,941 is 920128620.
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.
379 x 172 x 645 x 941 = 39565530660
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.
379 : 1, 379
172 : 1, 2, 4, 43, 86, 172
645 : 1, 3, 5, 15, 43, 129, 215, 645
941 : 1, 941
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 379,172,645,941, is 1.
Now, the common factors can be found like this.
379:379
172:2x 2x 43
645:3x 5x 43
941:941
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
43 = 43
Therefore, the value for common factors is 43.
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 = 39565530660/(1x43)
LCM = 39565530660/43
LCM = 920128620
Thus, we can understand that the LCM of 379,172,645,941 is 920128620.
