Given numbers are 742,477,380,318
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 742,477,380,318 is 1268820.
Find LCM of 742,477,380,318 with Prime Factorization
| 2 | 742, 477, 380, 318 |
| 3 | 371, 477, 190, 159 |
| 53 | 371, 53, 190, 159 |
| 7, 1, 190, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 53 x 7 x 1 x 190 x 3 = 1268820
Therefore, the lowest common multiple of 742,477,380,318 is 1268820.
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.
742 x 477 x 380 x 318 = 42769384560
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
477 : 1, 3, 9, 53, 159, 477
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
318 : 1, 2, 3, 6, 53, 106, 159, 318
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,477,380,318, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
477:3x 3x 53
380:2x 2x 5x 19
318:2x 3x 53
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 53x 53 = 33708
Therefore, the value for common factors is 33708.
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 = 42769384560/(1x33708)
LCM = 42769384560/33708
LCM = 1268820
Thus, we can understand that the LCM of 742,477,380,318 is 1268820.
