Find LCM of 781,330,638,319,922 with Prime Factorization
2 | 781, 330, 638, 319, 922 |
11 | 781, 165, 319, 319, 461 |
29 | 71, 15, 29, 29, 461 |
71, 15, 1, 1, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 71 x 15 x 1 x 1 x 461 = 313235670
Therefore, the lowest common multiple of 781,330,638,319,922 is 313235670.
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.
781 x 330 x 638 x 319 x 922 = 48362334505320
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.
781 : 1, 11, 71, 781
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
638 : 1, 2, 11, 22, 29, 58, 319, 638
319 : 1, 11, 29, 319
922 : 1, 2, 461, 922
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,330,638,319,922, is 1.
Now, the common factors can be found like this.
781:11x 71
330:2x 3x 5x 11
638:2x 11x 29
319:11x 29
922:2x 461
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 11x 11x 11x 29 = 154396
Therefore, the value for common factors is 154396.
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 = 48362334505320/(1x154396)
LCM = 48362334505320/154396
LCM = 313235670
Thus, we can understand that the LCM of 781,330,638,319,922 is 313235670.
