Given numbers are 694,916,765,939,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 694,916,765,939,784 is 14917182139440.
Find LCM of 694,916,765,939,784 with Prime Factorization
| 2 | 694, 916, 765, 939, 784 |
| 2 | 347, 458, 765, 939, 392 |
| 3 | 347, 229, 765, 939, 196 |
| 347, 229, 255, 313, 196 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 347 x 229 x 255 x 313 x 196 = 14917182139440
Therefore, the lowest common multiple of 694,916,765,939,784 is 14917182139440.
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.
694 x 916 x 765 x 939 x 784 = 358012371346560
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.
694 : 1, 2, 347, 694
916 : 1, 2, 4, 229, 458, 916
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
939 : 1, 3, 313, 939
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,916,765,939,784, is 1.
Now, the common factors can be found like this.
694:2x 347
916:2x 2x 229
765:3x 3x 5x 17
939:3x 313
784:2x 2x 2x 2x 7x 7
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 3 = 24
Therefore, the value for common factors is 24.
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 = 358012371346560/(1x24)
LCM = 358012371346560/24
LCM = 14917182139440
Thus, we can understand that the LCM of 694,916,765,939,784 is 14917182139440.
