Given numbers are 646,529,947,430,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,529,947,430,121 is 8419028879470.
Find LCM of 646,529,947,430,121 with Prime Factorization
| 2 | 646, 529, 947, 430, 121 |
| 323, 529, 947, 215, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 323 x 529 x 947 x 215 x 121 = 8419028879470
Therefore, the lowest common multiple of 646,529,947,430,121 is 8419028879470.
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.
646 x 529 x 947 x 430 x 121 = 16838057758940
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
529 : 1, 23, 529
947 : 1, 947
430 : 1, 2, 5, 10, 43, 86, 215, 430
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,529,947,430,121, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
529:23x 23
947:947
430:2x 5x 43
121:11x 11
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 = 16838057758940/(1x2)
LCM = 16838057758940/2
LCM = 8419028879470
Thus, we can understand that the LCM of 646,529,947,430,121 is 8419028879470.
