Given numbers are 743,843,640,916,248
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,843,640,916,248 is 2845728992640.
Find LCM of 743,843,640,916,248 with Prime Factorization
| 2 | 743, 843, 640, 916, 248 |
| 2 | 743, 843, 320, 458, 124 |
| 2 | 743, 843, 160, 229, 62 |
| 743, 843, 80, 229, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 743 x 843 x 80 x 229 x 31 = 2845728992640
Therefore, the lowest common multiple of 743,843,640,916,248 is 2845728992640.
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.
743 x 843 x 640 x 916 x 248 = 91063327764480
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.
743 : 1, 743
843 : 1, 3, 281, 843
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
916 : 1, 2, 4, 229, 458, 916
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,843,640,916,248, is 1.
Now, the common factors can be found like this.
743:743
843:3x 281
640:2x 2x 2x 2x 2x 2x 2x 5
916:2x 2x 229
248:2x 2x 2x 31
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 2x 2 = 32
Therefore, the value for common factors is 32.
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 = 91063327764480/(1x32)
LCM = 91063327764480/32
LCM = 2845728992640
Thus, we can understand that the LCM of 743,843,640,916,248 is 2845728992640.
