Given numbers are 475,786,470,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 475,786,470,688 is 6036322800.
Find LCM of 475,786,470,688 with Prime Factorization
| 2 | 475, 786, 470, 688 |
| 5 | 475, 393, 235, 344 |
| 95, 393, 47, 344 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 95 x 393 x 47 x 344 = 6036322800
Therefore, the lowest common multiple of 475,786,470,688 is 6036322800.
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.
475 x 786 x 470 x 688 = 120726456000
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.
475 : 1, 5, 19, 25, 95, 475
786 : 1, 2, 3, 6, 131, 262, 393, 786
470 : 1, 2, 5, 10, 47, 94, 235, 470
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 475,786,470,688, is 1.
Now, the common factors can be found like this.
475:5x 5x 19
786:2x 3x 131
470:2x 5x 47
688:2x 2x 2x 2x 43
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 5 = 20
Therefore, the value for common factors is 20.
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 = 120726456000/(1x20)
LCM = 120726456000/20
LCM = 6036322800
Thus, we can understand that the LCM of 475,786,470,688 is 6036322800.
