Given numbers are 262,398,838,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 262,398,838,138 is 1507361718.
Find LCM of 262,398,838,138 with Prime Factorization
2 | 262, 398, 838, 138 |
131, 199, 419, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 131 x 199 x 419 x 69 = 1507361718
Therefore, the lowest common multiple of 262,398,838,138 is 1507361718.
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.
262 x 398 x 838 x 138 = 12058893744
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.
262 : 1, 2, 131, 262
398 : 1, 2, 199, 398
838 : 1, 2, 419, 838
138 : 1, 2, 3, 6, 23, 46, 69, 138
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 262,398,838,138, is 2.
Now, the common factors can be found like this.
262:2x 131
398:2x 199
838:2x 419
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.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 12058893744/(2x4)
LCM = 12058893744/8
LCM = 1507361718
Thus, we can understand that the LCM of 262,398,838,138 is 1507361718.
