Given numbers are 347,680,558,340,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,680,558,340,784 is 6451618320.
Find LCM of 347,680,558,340,784 with Prime Factorization
| 2 | 347, 680, 558, 340, 784 |
| 2 | 347, 340, 279, 170, 392 |
| 2 | 347, 85, 279, 170, 196 |
| 5 | 347, 85, 279, 85, 98 |
| 17 | 347, 17, 279, 17, 98 |
| 347, 1, 279, 1, 98 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 347 x 1 x 279 x 1 x 98 = 6451618320
Therefore, the lowest common multiple of 347,680,558,340,784 is 6451618320.
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.
347 x 680 x 558 x 340 x 784 = 35096803660800
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.
347 : 1, 347
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,680,558,340,784, is 1.
Now, the common factors can be found like this.
347:347
680:2x 2x 2x 5x 17
558:2x 3x 3x 31
340:2x 2x 5x 17
784:2x 2x 2x 2x 7x 7
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 2x 2x 2x 2x 5x 17 = 5440
Therefore, the value for common factors is 5440.
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 = 35096803660800/(1x5440)
LCM = 35096803660800/5440
LCM = 6451618320
Thus, we can understand that the LCM of 347,680,558,340,784 is 6451618320.
