Given numbers are 760,399,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 760,399,681 is 3622920.
Find LCM of 760,399,681 with Prime Factorization
| 3 | 760, 399, 681 |
| 19 | 760, 133, 227 |
| 40, 7, 227 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 40 x 7 x 227 = 3622920
Therefore, the lowest common multiple of 760,399,681 is 3622920.
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.
760 x 399 x 681 = 206506440
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
399 : 1, 3, 7, 19, 21, 57, 133, 399
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,399,681, is 1.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
399:3x 7x 19
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19 = 57
Therefore, the value for common factors is 57.
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 = 206506440/(1x57)
LCM = 206506440/57
LCM = 3622920
Thus, we can understand that the LCM of 760,399,681 is 3622920.
