Find LCM of 156,638,672,899 with Prime Factorization
2 | 156, 638, 672, 899 |
2 | 78, 319, 336, 899 |
3 | 39, 319, 168, 899 |
29 | 13, 319, 56, 899 |
13, 11, 56, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 29 x 13 x 11 x 56 x 31 = 86390304
Therefore, the lowest common multiple of 156,638,672,899 is 86390304.
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.
156 x 638 x 672 x 899 = 60127651584
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
638 : 1, 2, 11, 22, 29, 58, 319, 638
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,638,672,899, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
638:2x 11x 29
672:2x 2x 2x 2x 2x 3x 7
899:29x 31
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 3x 29 = 696
Therefore, the value for common factors is 696.
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 = 60127651584/(1x696)
LCM = 60127651584/696
LCM = 86390304
Thus, we can understand that the LCM of 156,638,672,899 is 86390304.
