Given numbers are 343,252,190,142,554
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,252,190,142,554 is 23070571020.
Find LCM of 343,252,190,142,554 with Prime Factorization
| 2 | 343, 252, 190, 142, 554 |
| 7 | 343, 126, 95, 71, 277 |
| 49, 18, 95, 71, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 49 x 18 x 95 x 71 x 277 = 23070571020
Therefore, the lowest common multiple of 343,252,190,142,554 is 23070571020.
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 252 x 190 x 142 x 554 = 1291951977120
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
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
190 : 1, 2, 5, 10, 19, 38, 95, 190
142 : 1, 2, 71, 142
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,252,190,142,554, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
252:2x 2x 3x 3x 7
190:2x 5x 19
142:2x 71
554:2x 277
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 7 = 56
Therefore, the value for common factors is 56.
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 = 1291951977120/(1x56)
LCM = 1291951977120/56
LCM = 23070571020
Thus, we can understand that the LCM of 343,252,190,142,554 is 23070571020.
