Given numbers are 371,398,779,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 371,398,779,138 is 7936765158.
Find LCM of 371,398,779,138 with Prime Factorization
| 2 | 371, 398, 779, 138 |
| 371, 199, 779, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 371 x 199 x 779 x 69 = 7936765158
Therefore, the lowest common multiple of 371,398,779,138 is 7936765158.
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.
371 x 398 x 779 x 138 = 15873530316
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.
371 : 1, 7, 53, 371
398 : 1, 2, 199, 398
779 : 1, 19, 41, 779
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 371,398,779,138, is 1.
Now, the common factors can be found like this.
371:7x 53
398:2x 199
779:19x 41
138:2x 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.
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 = 15873530316/(1x2)
LCM = 15873530316/2
LCM = 7936765158
Thus, we can understand that the LCM of 371,398,779,138 is 7936765158.
