Given numbers are 221,130,754,771,361
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,130,754,771,361 is 17838233790.
Find LCM of 221,130,754,771,361 with Prime Factorization
2 | 221, 130, 754, 771, 361 |
13 | 221, 65, 377, 771, 361 |
17, 5, 29, 771, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 5 x 29 x 771 x 361 = 17838233790
Therefore, the lowest common multiple of 221,130,754,771,361 is 17838233790.
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.
221 x 130 x 754 x 771 x 361 = 6029323021020
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.
221 : 1, 13, 17, 221
130 : 1, 2, 5, 10, 13, 26, 65, 130
754 : 1, 2, 13, 26, 29, 58, 377, 754
771 : 1, 3, 257, 771
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,130,754,771,361, is 1.
Now, the common factors can be found like this.
221:13x 17
130:2x 5x 13
754:2x 13x 29
771:3x 257
361:19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 6029323021020/(1x338)
LCM = 6029323021020/338
LCM = 17838233790
Thus, we can understand that the LCM of 221,130,754,771,361 is 17838233790.
