Find LCM of 152,491,640,605,685 with Prime Factorization
| 2 | 152, 491, 640, 605, 685 |
| 2 | 76, 491, 320, 605, 685 |
| 2 | 38, 491, 160, 605, 685 |
| 5 | 19, 491, 80, 605, 685 |
| 19, 491, 16, 121, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 19 x 491 x 16 x 121 x 137 = 98973973120
Therefore, the lowest common multiple of 152,491,640,605,685 is 98973973120.
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.
152 x 491 x 640 x 605 x 685 = 19794794624000
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.
152 : 1, 2, 4, 8, 19, 38, 76, 152
491 : 1, 491
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
605 : 1, 5, 11, 55, 121, 605
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 152,491,640,605,685, is 1.
Now, the common factors can be found like this.
152:2x 2x 2x 19
491:491
640:2x 2x 2x 2x 2x 2x 2x 5
605:5x 11x 11
685:5x 137
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 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 19794794624000/(1x200)
LCM = 19794794624000/200
LCM = 98973973120
Thus, we can understand that the LCM of 152,491,640,605,685 is 98973973120.
