Given numbers are 851,815,295,449,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,815,295,449,690 is 110239382490.
Find LCM of 851,815,295,449,690 with Prime Factorization
| 5 | 851, 815, 295, 449, 690 |
| 23 | 851, 163, 59, 449, 138 |
| 37, 163, 59, 449, 6 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 37 x 163 x 59 x 449 x 6 = 110239382490
Therefore, the lowest common multiple of 851,815,295,449,690 is 110239382490.
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.
851 x 815 x 295 x 449 x 690 = 63387644931750
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.
851 : 1, 23, 37, 851
815 : 1, 5, 163, 815
295 : 1, 5, 59, 295
449 : 1, 449
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,815,295,449,690, is 1.
Now, the common factors can be found like this.
851:23x 37
815:5x 163
295:5x 59
449:449
690:2x 3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 23 = 575
Therefore, the value for common factors is 575.
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 = 63387644931750/(1x575)
LCM = 63387644931750/575
LCM = 110239382490
Thus, we can understand that the LCM of 851,815,295,449,690 is 110239382490.
