Given numbers are 747,139,378
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,139,378 is 4360986.
Find LCM of 747,139,378 with Prime Factorization
| 3 | 747, 139, 378 |
| 3 | 249, 139, 126 |
| 83, 139, 42 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 83 x 139 x 42 = 4360986
Therefore, the lowest common multiple of 747,139,378 is 4360986.
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.
747 x 139 x 378 = 39248874
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.
747 : 1, 3, 9, 83, 249, 747
139 : 1, 139
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,139,378, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
139:139
378:2x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 39248874/(1x9)
LCM = 39248874/9
LCM = 4360986
Thus, we can understand that the LCM of 747,139,378 is 4360986.
