Given numbers are 681,803,666,370
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,803,666,370 is 606995730.
Find LCM of 681,803,666,370 with Prime Factorization
| 2 | 681, 803, 666, 370 |
| 3 | 681, 803, 333, 185 |
| 37 | 227, 803, 111, 185 |
| 227, 803, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 37 x 227 x 803 x 3 x 5 = 606995730
Therefore, the lowest common multiple of 681,803,666,370 is 606995730.
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.
681 x 803 x 666 x 370 = 134753052060
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.
681 : 1, 3, 227, 681
803 : 1, 11, 73, 803
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,803,666,370, is 1.
Now, the common factors can be found like this.
681:3x 227
803:11x 73
666:2x 3x 3x 37
370:2x 5x 37
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 37 = 222
Therefore, the value for common factors is 222.
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 = 134753052060/(1x222)
LCM = 134753052060/222
LCM = 606995730
Thus, we can understand that the LCM of 681,803,666,370 is 606995730.
