Find LCM of 665,272,472,854,881 with Prime Factorization
| 2 | 665, 272, 472, 854, 881 |
| 2 | 665, 136, 236, 427, 881 |
| 2 | 665, 68, 118, 427, 881 |
| 7 | 665, 34, 59, 427, 881 |
| 95, 34, 59, 61, 881 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 95 x 34 x 59 x 61 x 881 = 573519652720
Therefore, the lowest common multiple of 665,272,472,854,881 is 573519652720.
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.
665 x 272 x 472 x 854 x 881 = 64234201104640
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
472 : 1, 2, 4, 8, 59, 118, 236, 472
854 : 1, 2, 7, 14, 61, 122, 427, 854
881 : 1, 881
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,272,472,854,881, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
272:2x 2x 2x 2x 17
472:2x 2x 2x 59
854:2x 7x 61
881:881
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 7 = 112
Therefore, the value for common factors is 112.
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 = 64234201104640/(1x112)
LCM = 64234201104640/112
LCM = 573519652720
Thus, we can understand that the LCM of 665,272,472,854,881 is 573519652720.
