The LCM of 338,620,983,156,765 is 15758807220.
Find LCM of 338,620,983,156,765 with Prime Factorization
| 2 | 338, 620, 983, 156, 765 |
| 2 | 169, 310, 983, 78, 765 |
| 3 | 169, 155, 983, 39, 765 |
| 5 | 169, 155, 983, 13, 255 |
| 13 | 169, 31, 983, 13, 51 |
| 1, 31, 983, 13, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 1 x 31 x 983 x 13 x 51 = 15758807220
Therefore, the lowest common multiple of 338,620,983,156,765 is 15758807220.
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 620 x 983 x 156 x 765 = 24583739263200
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
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
983 : 1, 983
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,620,983,156,765, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
620:2x 2x 5x 31
983:983
156:2x 2x 3x 13
765:3x 3x 5x 17
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 5x 13 = 1560
Therefore, the value for common factors is 1560.
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 = 24583739263200/(1x1560)
LCM = 24583739263200/1560
LCM = 15758807220
Thus, we can understand that the LCM of 338,620,983,156,765 is 15758807220.
