Find LCM of 697,905,291,640,104 with Prime Factorization
| 2 | 697, 905, 291, 640, 104 |
| 2 | 697, 905, 291, 320, 52 |
| 2 | 697, 905, 291, 160, 26 |
| 5 | 697, 905, 291, 80, 13 |
| 697, 181, 291, 16, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 697 x 181 x 291 x 16 x 13 = 305441235840
Therefore, the lowest common multiple of 697,905,291,640,104 is 305441235840.
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.
697 x 905 x 291 x 640 x 104 = 12217649433600
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.
697 : 1, 17, 41, 697
905 : 1, 5, 181, 905
291 : 1, 3, 97, 291
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
104 : 1, 2, 4, 8, 13, 26, 52, 104
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,905,291,640,104, is 1.
Now, the common factors can be found like this.
697:17x 41
905:5x 181
291:3x 97
640:2x 2x 2x 2x 2x 2x 2x 5
104:2x 2x 2x 13
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 5 = 40
Therefore, the value for common factors is 40.
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 = 12217649433600/(1x40)
LCM = 12217649433600/40
LCM = 305441235840
Thus, we can understand that the LCM of 697,905,291,640,104 is 305441235840.
