The LCM of 847,290,120,714 is 50108520.
Find LCM of 847,290,120,714 with Prime Factorization
| 2 | 847, 290, 120, 714 |
| 3 | 847, 145, 60, 357 |
| 5 | 847, 145, 20, 119 |
| 7 | 847, 29, 4, 119 |
| 121, 29, 4, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 121 x 29 x 4 x 17 = 50108520
Therefore, the lowest common multiple of 847,290,120,714 is 50108520.
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.
847 x 290 x 120 x 714 = 21045578400
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.
847 : 1, 7, 11, 77, 121, 847
290 : 1, 2, 5, 10, 29, 58, 145, 290
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,290,120,714, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
290:2x 5x 29
120:2x 2x 2x 3x 5
714:2x 3x 7x 17
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 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 21045578400/(1x420)
LCM = 21045578400/420
LCM = 50108520
Thus, we can understand that the LCM of 847,290,120,714 is 50108520.
