Given numbers are 653,341,638,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 653,341,638,993 is 12824628762.
Find LCM of 653,341,638,993 with Prime Factorization
11 | 653, 341, 638, 993 |
653, 31, 58, 993 |
Multiply the prime numbers at the bottom and the left side.
11 x 653 x 31 x 58 x 993 = 12824628762
Therefore, the lowest common multiple of 653,341,638,993 is 12824628762.
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.
653 x 341 x 638 x 993 = 141070916382
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.
653 : 1, 653
341 : 1, 11, 31, 341
638 : 1, 2, 11, 22, 29, 58, 319, 638
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 653,341,638,993, is 1.
Now, the common factors can be found like this.
653:653
341:11x 31
638:2x 11x 29
993:3x 331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 141070916382/(1x11)
LCM = 141070916382/11
LCM = 12824628762
Thus, we can understand that the LCM of 653,341,638,993 is 12824628762.
