The LCM of 315,634,505,770,247 is 54803819070.
Find LCM of 315,634,505,770,247 with Prime Factorization
| 2 | 315, 634, 505, 770, 247 |
| 5 | 315, 317, 505, 385, 247 |
| 7 | 63, 317, 101, 77, 247 |
| 9, 317, 101, 11, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 9 x 317 x 101 x 11 x 247 = 54803819070
Therefore, the lowest common multiple of 315,634,505,770,247 is 54803819070.
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.
315 x 634 x 505 x 770 x 247 = 19181336674500
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
634 : 1, 2, 317, 634
505 : 1, 5, 101, 505
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,634,505,770,247, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
634:2x 317
505:5x 101
770:2x 5x 7x 11
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7 = 350
Therefore, the value for common factors is 350.
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 = 19181336674500/(1x350)
LCM = 19181336674500/350
LCM = 54803819070
Thus, we can understand that the LCM of 315,634,505,770,247 is 54803819070.
