The LCM of 156,245,676,240 is 1987440.
Find LCM of 156,245,676,240 with Prime Factorization
| 2 | 156, 245, 676, 240 |
| 2 | 78, 245, 338, 120 |
| 3 | 39, 245, 169, 60 |
| 5 | 13, 245, 169, 20 |
| 13 | 13, 49, 169, 4 |
| 1, 49, 13, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 1 x 49 x 13 x 4 = 1987440
Therefore, the lowest common multiple of 156,245,676,240 is 1987440.
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.
156 x 245 x 676 x 240 = 6200812800
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
245 : 1, 5, 7, 35, 49, 245
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,245,676,240, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
245:5x 7x 7
676:2x 2x 13x 13
240:2x 2x 2x 2x 3x 5
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 2x 3x 5x 13 = 3120
Therefore, the value for common factors is 3120.
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 = 6200812800/(1x3120)
LCM = 6200812800/3120
LCM = 1987440
Thus, we can understand that the LCM of 156,245,676,240 is 1987440.
