Find LCM of 851,496,980,686,388 with Prime Factorization
| 2 | 851, 496, 980, 686, 388 |
| 2 | 851, 248, 490, 343, 194 |
| 7 | 851, 124, 245, 343, 97 |
| 7 | 851, 124, 35, 49, 97 |
| 851, 124, 5, 7, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 851 x 124 x 5 x 7 x 97 = 70217780080
Therefore, the lowest common multiple of 851,496,980,686,388 is 70217780080.
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.
851 x 496 x 980 x 686 x 388 = 110101479165440
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.
851 : 1, 23, 37, 851
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
686 : 1, 2, 7, 14, 49, 98, 343, 686
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,496,980,686,388, is 1.
Now, the common factors can be found like this.
851:23x 37
496:2x 2x 2x 2x 31
980:2x 2x 5x 7x 7
686:2x 7x 7x 7
388:2x 2x 97
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 2x 7x 7 = 1568
Therefore, the value for common factors is 1568.
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 = 110101479165440/(1x1568)
LCM = 110101479165440/1568
LCM = 70217780080
Thus, we can understand that the LCM of 851,496,980,686,388 is 70217780080.
