Find LCM of 476,105,492,690 with Prime Factorization
| 2 | 476, 105, 492, 690 |
| 2 | 238, 105, 246, 345 |
| 3 | 119, 105, 123, 345 |
| 5 | 119, 35, 41, 115 |
| 7 | 119, 7, 41, 23 |
| 17, 1, 41, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 17 x 1 x 41 x 23 = 6733020
Therefore, the lowest common multiple of 476,105,492,690 is 6733020.
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.
476 x 105 x 492 x 690 = 16967210400
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
105 : 1, 3, 5, 7, 15, 21, 35, 105
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,105,492,690, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
105:3x 5x 7
492:2x 2x 3x 41
690:2x 3x 5x 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 2x 2x 3x 3x 5x 7 = 2520
Therefore, the value for common factors is 2520.
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 = 16967210400/(1x2520)
LCM = 16967210400/2520
LCM = 6733020
Thus, we can understand that the LCM of 476,105,492,690 is 6733020.
