Find LCM of 156,245,373,642,392 with Prime Factorization
| 2 | 156, 245, 373, 642, 392 |
| 2 | 78, 245, 373, 321, 196 |
| 3 | 39, 245, 373, 321, 98 |
| 7 | 13, 245, 373, 107, 98 |
| 7 | 13, 35, 373, 107, 14 |
| 13, 5, 373, 107, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 7 x 13 x 5 x 373 x 107 x 2 = 3050796840
Therefore, the lowest common multiple of 156,245,373,642,392 is 3050796840.
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 373 x 642 x 392 = 3587737083840
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
373 : 1, 373
642 : 1, 2, 3, 6, 107, 214, 321, 642
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,245,373,642,392, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
245:5x 7x 7
373:373
642:2x 3x 107
392:2x 2x 2x 7x 7
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 7x 7 = 1176
Therefore, the value for common factors is 1176.
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 = 3587737083840/(1x1176)
LCM = 3587737083840/1176
LCM = 3050796840
Thus, we can understand that the LCM of 156,245,373,642,392 is 3050796840.
