Find LCM of 786,478,693,671,610 with Prime Factorization
| 2 | 786, 478, 693, 671, 610 |
| 3 | 393, 239, 693, 671, 305 |
| 11 | 131, 239, 231, 671, 305 |
| 61 | 131, 239, 21, 61, 305 |
| 131, 239, 21, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 61 x 131 x 239 x 21 x 1 x 5 = 13235253570
Therefore, the lowest common multiple of 786,478,693,671,610 is 13235253570.
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.
786 x 478 x 693 x 671 x 610 = 106570261745640
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
478 : 1, 2, 239, 478
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
671 : 1, 11, 61, 671
610 : 1, 2, 5, 10, 61, 122, 305, 610
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,478,693,671,610, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
478:2x 239
693:3x 3x 7x 11
671:11x 61
610:2x 5x 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 2x 3x 11x 61 = 8052
Therefore, the value for common factors is 8052.
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 = 106570261745640/(1x8052)
LCM = 106570261745640/8052
LCM = 13235253570
Thus, we can understand that the LCM of 786,478,693,671,610 is 13235253570.
