Given numbers are 492,286,641,138,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 492,286,641,138,641 is 1037258508.
Find LCM of 492,286,641,138,641 with Prime Factorization
| 2 | 492, 286, 641, 138, 641 |
| 3 | 246, 143, 641, 69, 641 |
| 641 | 82, 143, 641, 23, 641 |
| 82, 143, 1, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 641 x 82 x 143 x 1 x 23 x 1 = 1037258508
Therefore, the lowest common multiple of 492,286,641,138,641 is 1037258508.
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.
492 x 286 x 641 x 138 x 641 = 7978592443536
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.
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
286 : 1, 2, 11, 13, 22, 26, 143, 286
641 : 1, 641
138 : 1, 2, 3, 6, 23, 46, 69, 138
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,286,641,138,641, is 1.
Now, the common factors can be found like this.
492:2x 2x 3x 41
286:2x 11x 13
641:641
138:2x 3x 23
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 641 = 7692
Therefore, the value for common factors is 7692.
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 = 7978592443536/(1x7692)
LCM = 7978592443536/7692
LCM = 1037258508
Thus, we can understand that the LCM of 492,286,641,138,641 is 1037258508.
