Given numbers are 345,661,634,552
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,661,634,552 is 578322120.
Find LCM of 345,661,634,552 with Prime Factorization
| 2 | 345, 661, 634, 552 |
| 3 | 345, 661, 317, 276 |
| 23 | 115, 661, 317, 92 |
| 5, 661, 317, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 5 x 661 x 317 x 4 = 578322120
Therefore, the lowest common multiple of 345,661,634,552 is 578322120.
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.
345 x 661 x 634 x 552 = 79808452560
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
661 : 1, 661
634 : 1, 2, 317, 634
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,661,634,552, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
661:661
634:2x 317
552:2x 2x 2x 3x 23
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 23 = 138
Therefore, the value for common factors is 138.
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 = 79808452560/(1x138)
LCM = 79808452560/138
LCM = 578322120
Thus, we can understand that the LCM of 345,661,634,552 is 578322120.
