Given numbers are 661,642,559,146
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,642,559,146 is 17316940134.
Find LCM of 661,642,559,146 with Prime Factorization
2 | 661, 642, 559, 146 |
661, 321, 559, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 661 x 321 x 559 x 73 = 17316940134
Therefore, the lowest common multiple of 661,642,559,146 is 17316940134.
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.
661 x 642 x 559 x 146 = 34633880268
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.
661 : 1, 661
642 : 1, 2, 3, 6, 107, 214, 321, 642
559 : 1, 13, 43, 559
146 : 1, 2, 73, 146
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,642,559,146, is 1.
Now, the common factors can be found like this.
661:661
642:2x 3x 107
559:13x 43
146:2x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 34633880268/(1x2)
LCM = 34633880268/2
LCM = 17316940134
Thus, we can understand that the LCM of 661,642,559,146 is 17316940134.
