Given numbers are 821,821,470,718
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,821,470,718 is 138527330.
Find LCM of 821,821,470,718 with Prime Factorization
2 | 821, 821, 470, 718 |
821 | 821, 821, 235, 359 |
1, 1, 235, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 821 x 1 x 1 x 235 x 359 = 138527330
Therefore, the lowest common multiple of 821,821,470,718 is 138527330.
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.
821 x 821 x 470 x 718 = 227461875860
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.
821 : 1, 821
821 : 1, 821
470 : 1, 2, 5, 10, 47, 94, 235, 470
718 : 1, 2, 359, 718
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,821,470,718, is 1.
Now, the common factors can be found like this.
821:821
821:821
470:2x 5x 47
718:2x 359
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 821 = 1642
Therefore, the value for common factors is 1642.
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 = 227461875860/(1x1642)
LCM = 227461875860/1642
LCM = 138527330
Thus, we can understand that the LCM of 821,821,470,718 is 138527330.
