Given numbers are 818,918,121,425,619
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 818,918,121,425,619 is 703043208450.
Find LCM of 818,918,121,425,619 with Prime Factorization
| 2 | 818, 918, 121, 425, 619 |
| 17 | 409, 459, 121, 425, 619 |
| 409, 27, 121, 25, 619 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 409 x 27 x 121 x 25 x 619 = 703043208450
Therefore, the lowest common multiple of 818,918,121,425,619 is 703043208450.
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.
818 x 918 x 121 x 425 x 619 = 23903469087300
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.
818 : 1, 2, 409, 818
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
121 : 1, 11, 121
425 : 1, 5, 17, 25, 85, 425
619 : 1, 619
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,918,121,425,619, is 1.
Now, the common factors can be found like this.
818:2x 409
918:2x 3x 3x 3x 17
121:11x 11
425:5x 5x 17
619:619
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 23903469087300/(1x34)
LCM = 23903469087300/34
LCM = 703043208450
Thus, we can understand that the LCM of 818,918,121,425,619 is 703043208450.
