Given numbers are 684,130,687,572
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,130,687,572 is 111994740.
Find LCM of 684,130,687,572 with Prime Factorization
2 | 684, 130, 687, 572 |
2 | 342, 65, 687, 286 |
3 | 171, 65, 687, 143 |
13 | 57, 65, 229, 143 |
57, 5, 229, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 57 x 5 x 229 x 11 = 111994740
Therefore, the lowest common multiple of 684,130,687,572 is 111994740.
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.
684 x 130 x 687 x 572 = 34942358880
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
130 : 1, 2, 5, 10, 13, 26, 65, 130
687 : 1, 3, 229, 687
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,130,687,572, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
130:2x 5x 13
687:3x 229
572:2x 2x 11x 13
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 13 = 312
Therefore, the value for common factors is 312.
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 = 34942358880/(1x312)
LCM = 34942358880/312
LCM = 111994740
Thus, we can understand that the LCM of 684,130,687,572 is 111994740.
