Given numbers are 395,554,561,750
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 395,554,561,750 is 3069090750.
Find LCM of 395,554,561,750 with Prime Factorization
| 2 | 395, 554, 561, 750 |
| 3 | 395, 277, 561, 375 |
| 5 | 395, 277, 187, 125 |
| 79, 277, 187, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 79 x 277 x 187 x 25 = 3069090750
Therefore, the lowest common multiple of 395,554,561,750 is 3069090750.
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.
395 x 554 x 561 x 750 = 92072722500
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.
395 : 1, 5, 79, 395
554 : 1, 2, 277, 554
561 : 1, 3, 11, 17, 33, 51, 187, 561
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,554,561,750, is 1.
Now, the common factors can be found like this.
395:5x 79
554:2x 277
561:3x 11x 17
750:2x 3x 5x 5x 5
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 5 = 30
Therefore, the value for common factors is 30.
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 = 92072722500/(1x30)
LCM = 92072722500/30
LCM = 3069090750
Thus, we can understand that the LCM of 395,554,561,750 is 3069090750.
