Given numbers are 498,798,821,147
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 498,798,821,147 is 380646798.
Find LCM of 498,798,821,147 with Prime Factorization
| 2 | 498, 798, 821, 147 |
| 3 | 249, 399, 821, 147 |
| 7 | 83, 133, 821, 49 |
| 83, 19, 821, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 83 x 19 x 821 x 7 = 380646798
Therefore, the lowest common multiple of 498,798,821,147 is 380646798.
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.
498 x 798 x 821 x 147 = 47961496548
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.
498 : 1, 2, 3, 6, 83, 166, 249, 498
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
821 : 1, 821
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 498,798,821,147, is 1.
Now, the common factors can be found like this.
498:2x 3x 83
798:2x 3x 7x 19
821:821
147:3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 47961496548/(1x126)
LCM = 47961496548/126
LCM = 380646798
Thus, we can understand that the LCM of 498,798,821,147 is 380646798.
