Find LCM of 157,738,196,660,931 with Prime Factorization
| 2 | 157, 738, 196, 660, 931 |
| 2 | 157, 369, 98, 330, 931 |
| 3 | 157, 369, 49, 165, 931 |
| 7 | 157, 123, 49, 55, 931 |
| 7 | 157, 123, 7, 55, 133 |
| 157, 123, 1, 55, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 7 x 157 x 123 x 1 x 55 x 19 = 11865837060
Therefore, the lowest common multiple of 157,738,196,660,931 is 11865837060.
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.
157 x 738 x 196 x 660 x 931 = 13954224382560
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.
157 : 1, 157
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,738,196,660,931, is 1.
Now, the common factors can be found like this.
157:157
738:2x 3x 3x 41
196:2x 2x 7x 7
660:2x 2x 3x 5x 11
931:7x 7x 19
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 = 13954224382560/(1x1176)
LCM = 13954224382560/1176
LCM = 11865837060
Thus, we can understand that the LCM of 157,738,196,660,931 is 11865837060.
