Given numbers are 680,541,398,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 680,541,398,687 is 50293978440.
Find LCM of 680,541,398,687 with Prime Factorization
2 | 680, 541, 398, 687 |
340, 541, 199, 687 |
Multiply the prime numbers at the bottom and the left side.
2 x 340 x 541 x 199 x 687 = 50293978440
Therefore, the lowest common multiple of 680,541,398,687 is 50293978440.
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.
680 x 541 x 398 x 687 = 100587956880
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
541 : 1, 541
398 : 1, 2, 199, 398
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,541,398,687, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
541:541
398:2x 199
687:3x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 100587956880/(1x2)
LCM = 100587956880/2
LCM = 50293978440
Thus, we can understand that the LCM of 680,541,398,687 is 50293978440.
