Given numbers are 254,516,438,979,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 254,516,438,979,220 is 23416877220.
Find LCM of 254,516,438,979,220 with Prime Factorization
| 2 | 254, 516, 438, 979, 220 |
| 2 | 127, 258, 219, 979, 110 |
| 3 | 127, 129, 219, 979, 55 |
| 11 | 127, 43, 73, 979, 55 |
| 127, 43, 73, 89, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 127 x 43 x 73 x 89 x 5 = 23416877220
Therefore, the lowest common multiple of 254,516,438,979,220 is 23416877220.
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.
254 x 516 x 438 x 979 x 220 = 12364111172160
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.
254 : 1, 2, 127, 254
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
438 : 1, 2, 3, 6, 73, 146, 219, 438
979 : 1, 11, 89, 979
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,516,438,979,220, is 1.
Now, the common factors can be found like this.
254:2x 127
516:2x 2x 3x 43
438:2x 3x 73
979:11x 89
220:2x 2x 5x 11
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 2x 2x 3x 11 = 528
Therefore, the value for common factors is 528.
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 = 12364111172160/(1x528)
LCM = 12364111172160/528
LCM = 23416877220
Thus, we can understand that the LCM of 254,516,438,979,220 is 23416877220.
