Given numbers are 377,157,442,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 377,157,442,221 is 2012426.
Find LCM of 377,157,442,221 with Prime Factorization
| 13 | 377, 157, 442, 221 |
| 17 | 29, 157, 34, 17 |
| 29, 157, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 29 x 157 x 2 x 1 = 2012426
Therefore, the lowest common multiple of 377,157,442,221 is 2012426.
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.
377 x 157 x 442 x 221 = 5781699898
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.
377 : 1, 13, 29, 377
157 : 1, 157
442 : 1, 2, 13, 17, 26, 34, 221, 442
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 377,157,442,221, is 1.
Now, the common factors can be found like this.
377:13x 29
157:157
442:2x 13x 17
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13x 17 = 2873
Therefore, the value for common factors is 2873.
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 = 5781699898/(1x2873)
LCM = 5781699898/2873
LCM = 2012426
Thus, we can understand that the LCM of 377,157,442,221 is 2012426.
