Given numbers are 254,839,672,654,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 254,839,672,654,988 is 1927784153568.
Find LCM of 254,839,672,654,988 with Prime Factorization
| 2 | 254, 839, 672, 654, 988 |
| 2 | 127, 839, 336, 327, 494 |
| 3 | 127, 839, 168, 327, 247 |
| 127, 839, 56, 109, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 127 x 839 x 56 x 109 x 247 = 1927784153568
Therefore, the lowest common multiple of 254,839,672,654,988 is 1927784153568.
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 839 x 672 x 654 x 988 = 92533639371264
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
839 : 1, 839
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
654 : 1, 2, 3, 6, 109, 218, 327, 654
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,839,672,654,988, is 1.
Now, the common factors can be found like this.
254:2x 127
839:839
672:2x 2x 2x 2x 2x 3x 7
654:2x 3x 109
988:2x 2x 13x 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 2x 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 92533639371264/(1x48)
LCM = 92533639371264/48
LCM = 1927784153568
Thus, we can understand that the LCM of 254,839,672,654,988 is 1927784153568.
