Find LCM of 477,481,355,142,702 with Prime Factorization
| 2 | 477, 481, 355, 142, 702 |
| 3 | 477, 481, 355, 71, 351 |
| 3 | 159, 481, 355, 71, 117 |
| 13 | 53, 481, 355, 71, 39 |
| 71 | 53, 37, 355, 71, 3 |
| 53, 37, 5, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 71 x 53 x 37 x 5 x 1 x 3 = 488700810
Therefore, the lowest common multiple of 477,481,355,142,702 is 488700810.
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.
477 x 481 x 355 x 142 x 702 = 8119275257340
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.
477 : 1, 3, 9, 53, 159, 477
481 : 1, 13, 37, 481
355 : 1, 5, 71, 355
142 : 1, 2, 71, 142
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 477,481,355,142,702, is 1.
Now, the common factors can be found like this.
477:3x 3x 53
481:13x 37
355:5x 71
142:2x 71
702:2x 3x 3x 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 3x 3x 13x 71 = 16614
Therefore, the value for common factors is 16614.
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 = 8119275257340/(1x16614)
LCM = 8119275257340/16614
LCM = 488700810
Thus, we can understand that the LCM of 477,481,355,142,702 is 488700810.
