Given numbers are 555,640,398,318
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 555,640,398,318 is 749258880.
Find LCM of 555,640,398,318 with Prime Factorization
| 2 | 555, 640, 398, 318 |
| 3 | 555, 320, 199, 159 |
| 5 | 185, 320, 199, 53 |
| 37, 64, 199, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 37 x 64 x 199 x 53 = 749258880
Therefore, the lowest common multiple of 555,640,398,318 is 749258880.
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.
555 x 640 x 398 x 318 = 44955532800
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.
555 : 1, 3, 5, 15, 37, 111, 185, 555
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
398 : 1, 2, 199, 398
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 555,640,398,318, is 1.
Now, the common factors can be found like this.
555:3x 5x 37
640:2x 2x 2x 2x 2x 2x 2x 5
398:2x 199
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 5 = 60
Therefore, the value for common factors is 60.
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 = 44955532800/(1x60)
LCM = 44955532800/60
LCM = 749258880
Thus, we can understand that the LCM of 555,640,398,318 is 749258880.
