Given numbers are 561,659,289,947,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,659,289,947,640 is 3809141888640.
Find LCM of 561,659,289,947,640 with Prime Factorization
17 | 561, 659, 289, 947, 640 |
33, 659, 17, 947, 640 |
Multiply the prime numbers at the bottom and the left side.
17 x 33 x 659 x 17 x 947 x 640 = 3809141888640
Therefore, the lowest common multiple of 561,659,289,947,640 is 3809141888640.
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.
561 x 659 x 289 x 947 x 640 = 64755412106880
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
659 : 1, 659
289 : 1, 17, 289
947 : 1, 947
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,659,289,947,640, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
659:659
289:17x 17
947:947
640:2x 2x 2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 64755412106880/(1x17)
LCM = 64755412106880/17
LCM = 3809141888640
Thus, we can understand that the LCM of 561,659,289,947,640 is 3809141888640.
