Find LCM of 805,736,635,658 with Prime Factorization
| 2 | 805, 736, 635, 658 |
| 5 | 805, 368, 635, 329 |
| 7 | 161, 368, 127, 329 |
| 23 | 23, 368, 127, 47 |
| 1, 16, 127, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 23 x 1 x 16 x 127 x 47 = 153761440
Therefore, the lowest common multiple of 805,736,635,658 is 153761440.
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.
805 x 736 x 635 x 658 = 247555918400
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
635 : 1, 5, 127, 635
658 : 1, 2, 7, 14, 47, 94, 329, 658
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,736,635,658, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
736:2x 2x 2x 2x 2x 23
635:5x 127
658:2x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 23 = 1610
Therefore, the value for common factors is 1610.
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 = 247555918400/(1x1610)
LCM = 247555918400/1610
LCM = 153761440
Thus, we can understand that the LCM of 805,736,635,658 is 153761440.
