Given numbers are 847,470,646,475
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 847,470,646,475 is 642915350.
Find LCM of 847,470,646,475 with Prime Factorization
| 2 | 847, 470, 646, 475 |
| 5 | 847, 235, 323, 475 |
| 19 | 847, 47, 323, 95 |
| 847, 47, 17, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 847 x 47 x 17 x 5 = 642915350
Therefore, the lowest common multiple of 847,470,646,475 is 642915350.
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 470 x 646 x 475 = 122153916500
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
470 : 1, 2, 5, 10, 47, 94, 235, 470
646 : 1, 2, 17, 19, 34, 38, 323, 646
475 : 1, 5, 19, 25, 95, 475
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,470,646,475, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
470:2x 5x 47
646:2x 17x 19
475:5x 5x 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 19 = 190
Therefore, the value for common factors is 190.
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 = 122153916500/(1x190)
LCM = 122153916500/190
LCM = 642915350
Thus, we can understand that the LCM of 847,470,646,475 is 642915350.
