Given numbers are 343,390,409,156,279
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,390,409,156,279 is 10176418980.
Find LCM of 343,390,409,156,279 with Prime Factorization
| 2 | 343, 390, 409, 156, 279 |
| 3 | 343, 195, 409, 78, 279 |
| 13 | 343, 65, 409, 26, 93 |
| 343, 5, 409, 2, 93 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 343 x 5 x 409 x 2 x 93 = 10176418980
Therefore, the lowest common multiple of 343,390,409,156,279 is 10176418980.
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.
343 x 390 x 409 x 156 x 279 = 2381282041320
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.
343 : 1, 7, 49, 343
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
409 : 1, 409
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
279 : 1, 3, 9, 31, 93, 279
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,390,409,156,279, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
390:2x 3x 5x 13
409:409
156:2x 2x 3x 13
279:3x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 2381282041320/(1x234)
LCM = 2381282041320/234
LCM = 10176418980
Thus, we can understand that the LCM of 343,390,409,156,279 is 10176418980.
