The LCM of 894,638,426,781 is 20248206.
Find LCM of 894,638,426,781 with Prime Factorization
| 2 | 894, 638, 426, 781 |
| 3 | 447, 319, 213, 781 |
| 11 | 149, 319, 71, 781 |
| 71 | 149, 29, 71, 71 |
| 149, 29, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 71 x 149 x 29 x 1 x 1 = 20248206
Therefore, the lowest common multiple of 894,638,426,781 is 20248206.
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.
894 x 638 x 426 x 781 = 189766186632
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.
894 : 1, 2, 3, 6, 149, 298, 447, 894
638 : 1, 2, 11, 22, 29, 58, 319, 638
426 : 1, 2, 3, 6, 71, 142, 213, 426
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,638,426,781, is 1.
Now, the common factors can be found like this.
894:2x 3x 149
638:2x 11x 29
426:2x 3x 71
781:11x 71
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 3x 11x 71 = 9372
Therefore, the value for common factors is 9372.
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 = 189766186632/(1x9372)
LCM = 189766186632/9372
LCM = 20248206
Thus, we can understand that the LCM of 894,638,426,781 is 20248206.
