Find LCM of 672,427,152,389 with Prime Factorization
| 2 | 672, 427, 152, 389 |
| 2 | 336, 427, 76, 389 |
| 2 | 168, 427, 38, 389 |
| 7 | 84, 427, 19, 389 |
| 12, 61, 19, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 12 x 61 x 19 x 389 = 302971872
Therefore, the lowest common multiple of 672,427,152,389 is 302971872.
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.
672 x 427 x 152 x 389 = 16966424832
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.
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
427 : 1, 7, 61, 427
152 : 1, 2, 4, 8, 19, 38, 76, 152
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,427,152,389, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
427:7x 61
152:2x 2x 2x 19
389:389
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 7 = 56
Therefore, the value for common factors is 56.
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 = 16966424832/(1x56)
LCM = 16966424832/56
LCM = 302971872
Thus, we can understand that the LCM of 672,427,152,389 is 302971872.
