The LCM of 338,355,624,639,786 is 1131745680.
Find LCM of 338,355,624,639,786 with Prime Factorization
| 2 | 338, 355, 624, 639, 786 |
| 3 | 169, 355, 312, 639, 393 |
| 13 | 169, 355, 104, 213, 131 |
| 71 | 13, 355, 8, 213, 131 |
| 13, 5, 8, 3, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 71 x 13 x 5 x 8 x 3 x 131 = 1131745680
Therefore, the lowest common multiple of 338,355,624,639,786 is 1131745680.
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.
338 x 355 x 624 x 639 x 786 = 37605645455040
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.
338 : 1, 2, 13, 26, 169, 338
355 : 1, 5, 71, 355
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
639 : 1, 3, 9, 71, 213, 639
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,355,624,639,786, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
355:5x 71
624:2x 2x 2x 2x 3x 13
639:3x 3x 71
786:2x 3x 131
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 3x 13x 71 = 33228
Therefore, the value for common factors is 33228.
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 = 37605645455040/(1x33228)
LCM = 37605645455040/33228
LCM = 1131745680
Thus, we can understand that the LCM of 338,355,624,639,786 is 1131745680.
