Find LCM of 126,693,916,671 with Prime Factorization
| 2 | 126, 693, 916, 671 |
| 3 | 63, 693, 458, 671 |
| 3 | 21, 231, 458, 671 |
| 7 | 7, 77, 458, 671 |
| 11 | 1, 11, 458, 671 |
| 1, 1, 458, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 11 x 1 x 1 x 458 x 61 = 38722068
Therefore, the lowest common multiple of 126,693,916,671 is 38722068.
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.
126 x 693 x 916 x 671 = 53668786248
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
916 : 1, 2, 4, 229, 458, 916
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,693,916,671, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
693:3x 3x 7x 11
916:2x 2x 229
671:11x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 11 = 1386
Therefore, the value for common factors is 1386.
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 = 53668786248/(1x1386)
LCM = 53668786248/1386
LCM = 38722068
Thus, we can understand that the LCM of 126,693,916,671 is 38722068.
