Find LCM of 492,286,242,156 with Prime Factorization
| 2 | 492, 286, 242, 156 |
| 2 | 246, 143, 121, 78 |
| 3 | 123, 143, 121, 39 |
| 11 | 41, 143, 121, 13 |
| 13 | 41, 13, 11, 13 |
| 41, 1, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 41 x 1 x 11 x 1 = 773916
Therefore, the lowest common multiple of 492,286,242,156 is 773916.
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 242 x 156 = 5312159424
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
242 : 1, 2, 11, 22, 121, 242
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,286,242,156, is 2.
Now, the common factors can be found like this.
492:2x 2x 3x 41
286:2x 11x 13
242:2x 11x 11
156:2x 2x 3x 13
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 2x 3x 11x 13 = 3432
Therefore, the value for common factors is 3432.
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 = 5312159424/(2x3432)
LCM = 5312159424/6864
LCM = 773916
Thus, we can understand that the LCM of 492,286,242,156 is 773916.
