Given numbers are 247,672,637,746
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,672,637,746 is 433384224.
Find LCM of 247,672,637,746 with Prime Factorization
| 2 | 247, 672, 637, 746 |
| 7 | 247, 336, 637, 373 |
| 13 | 247, 48, 91, 373 |
| 19, 48, 7, 373 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 19 x 48 x 7 x 373 = 433384224
Therefore, the lowest common multiple of 247,672,637,746 is 433384224.
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.
247 x 672 x 637 x 746 = 78875928768
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.
247 : 1, 13, 19, 247
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
637 : 1, 7, 13, 49, 91, 637
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,672,637,746, is 1.
Now, the common factors can be found like this.
247:13x 19
672:2x 2x 2x 2x 2x 3x 7
637:7x 7x 13
746:2x 373
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 13 = 182
Therefore, the value for common factors is 182.
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 = 78875928768/(1x182)
LCM = 78875928768/182
LCM = 433384224
Thus, we can understand that the LCM of 247,672,637,746 is 433384224.
