Find LCM of 188,392,987,221,653 with Prime Factorization
2 | 188, 392, 987, 221, 653 |
2 | 94, 196, 987, 221, 653 |
7 | 47, 98, 987, 221, 653 |
47 | 47, 14, 141, 221, 653 |
1, 14, 3, 221, 653 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 47 x 1 x 14 x 3 x 221 x 653 = 7976468136
Therefore, the lowest common multiple of 188,392,987,221,653 is 7976468136.
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 392 x 987 x 221 x 653 = 10497032066976
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
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
987 : 1, 3, 7, 21, 47, 141, 329, 987
221 : 1, 13, 17, 221
653 : 1, 653
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 188,392,987,221,653, is 1.
Now, the common factors can be found like this.
188:2x 2x 47
392:2x 2x 2x 7x 7
987:3x 7x 47
221:13x 17
653:653
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 7x 47 = 1316
Therefore, the value for common factors is 1316.
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 = 10497032066976/(1x1316)
LCM = 10497032066976/1316
LCM = 7976468136
Thus, we can understand that the LCM of 188,392,987,221,653 is 7976468136.
