The LCM of 347,840,978,175 is 237556200.
Find LCM of 347,840,978,175 with Prime Factorization
| 2 | 347, 840, 978, 175 |
| 3 | 347, 420, 489, 175 |
| 5 | 347, 140, 163, 175 |
| 7 | 347, 28, 163, 35 |
| 347, 4, 163, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 347 x 4 x 163 x 5 = 237556200
Therefore, the lowest common multiple of 347,840,978,175 is 237556200.
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 840 x 978 x 175 = 49886802000
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
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
978 : 1, 2, 3, 6, 163, 326, 489, 978
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,840,978,175, is 1.
Now, the common factors can be found like this.
347:347
840:2x 2x 2x 3x 5x 7
978:2x 3x 163
175:5x 5x 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 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 49886802000/(1x210)
LCM = 49886802000/210
LCM = 237556200
Thus, we can understand that the LCM of 347,840,978,175 is 237556200.
