Find LCM of 188,915,145,870,980 with Prime Factorization
| 2 | 188, 915, 145, 870, 980 |
| 2 | 94, 915, 145, 435, 490 |
| 3 | 47, 915, 145, 435, 245 |
| 5 | 47, 305, 145, 145, 245 |
| 29 | 47, 61, 29, 29, 49 |
| 47, 61, 1, 1, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 29 x 47 x 61 x 1 x 1 x 49 = 244440420
Therefore, the lowest common multiple of 188,915,145,870,980 is 244440420.
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.
188 x 915 x 145 x 870 x 980 = 21266316540000
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.
188 : 1, 2, 4, 47, 94, 188
915 : 1, 3, 5, 15, 61, 183, 305, 915
145 : 1, 5, 29, 145
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 188,915,145,870,980, is 1.
Now, the common factors can be found like this.
188:2x 2x 47
915:3x 5x 61
145:5x 29
870:2x 3x 5x 29
980:2x 2x 5x 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 5x 5x 5x 29 = 87000
Therefore, the value for common factors is 87000.
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 = 21266316540000/(1x87000)
LCM = 21266316540000/87000
LCM = 244440420
Thus, we can understand that the LCM of 188,915,145,870,980 is 244440420.
