Given numbers are 578,381,368,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,381,368,342 is 2309646384.
Find LCM of 578,381,368,342 with Prime Factorization
| 2 | 578, 381, 368, 342 |
| 3 | 289, 381, 184, 171 |
| 289, 127, 184, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 289 x 127 x 184 x 57 = 2309646384
Therefore, the lowest common multiple of 578,381,368,342 is 2309646384.
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.
578 x 381 x 368 x 342 = 27715756608
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.
578 : 1, 2, 17, 34, 289, 578
381 : 1, 3, 127, 381
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,381,368,342, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
381:3x 127
368:2x 2x 2x 2x 23
342:2x 3x 3x 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 3 = 12
Therefore, the value for common factors is 12.
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 = 27715756608/(1x12)
LCM = 27715756608/12
LCM = 2309646384
Thus, we can understand that the LCM of 578,381,368,342 is 2309646384.
