Find LCM of 561,767,902,344,688 with Prime Factorization
| 2 | 561, 767, 902, 344, 688 |
| 2 | 561, 767, 451, 172, 344 |
| 2 | 561, 767, 451, 86, 172 |
| 11 | 561, 767, 451, 43, 86 |
| 43 | 51, 767, 41, 43, 86 |
| 51, 767, 41, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 43 x 51 x 767 x 41 x 1 x 2 = 12137535696
Therefore, the lowest common multiple of 561,767,902,344,688 is 12137535696.
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.
561 x 767 x 902 x 344 x 688 = 91856870147328
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
767 : 1, 13, 59, 767
902 : 1, 2, 11, 22, 41, 82, 451, 902
344 : 1, 2, 4, 8, 43, 86, 172, 344
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,767,902,344,688, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
767:13x 59
902:2x 11x 41
344:2x 2x 2x 43
688:2x 2x 2x 2x 43
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 2x 11x 43 = 7568
Therefore, the value for common factors is 7568.
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 = 91856870147328/(1x7568)
LCM = 91856870147328/7568
LCM = 12137535696
Thus, we can understand that the LCM of 561,767,902,344,688 is 12137535696.
