Given numbers are 746,378,873,432
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 746,378,873,432 is 109411344.
Find LCM of 746,378,873,432 with Prime Factorization
| 2 | 746, 378, 873, 432 |
| 3 | 373, 189, 873, 216 |
| 3 | 373, 63, 291, 72 |
| 3 | 373, 21, 97, 24 |
| 373, 7, 97, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 373 x 7 x 97 x 8 = 109411344
Therefore, the lowest common multiple of 746,378,873,432 is 109411344.
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.
746 x 378 x 873 x 432 = 106347826368
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.
746 : 1, 2, 373, 746
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
873 : 1, 3, 9, 97, 291, 873
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,378,873,432, is 1.
Now, the common factors can be found like this.
746:2x 373
378:2x 3x 3x 3x 7
873:3x 3x 97
432:2x 2x 2x 2x 3x 3x 3
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 3x 3x 3x 3x 3 = 972
Therefore, the value for common factors is 972.
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 = 106347826368/(1x972)
LCM = 106347826368/972
LCM = 109411344
Thus, we can understand that the LCM of 746,378,873,432 is 109411344.
