Given numbers are 321,748,262,847,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,748,262,847,820 is 496503726180.
Find LCM of 321,748,262,847,820 with Prime Factorization
| 2 | 321, 748, 262, 847, 820 |
| 2 | 321, 374, 131, 847, 410 |
| 11 | 321, 187, 131, 847, 205 |
| 321, 17, 131, 77, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 321 x 17 x 131 x 77 x 205 = 496503726180
Therefore, the lowest common multiple of 321,748,262,847,820 is 496503726180.
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.
321 x 748 x 262 x 847 x 820 = 43692327903840
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.
321 : 1, 3, 107, 321
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
262 : 1, 2, 131, 262
847 : 1, 7, 11, 77, 121, 847
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,748,262,847,820, is 1.
Now, the common factors can be found like this.
321:3x 107
748:2x 2x 11x 17
262:2x 131
847:7x 11x 11
820:2x 2x 5x 41
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 2x 11 = 88
Therefore, the value for common factors is 88.
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 = 43692327903840/(1x88)
LCM = 43692327903840/88
LCM = 496503726180
Thus, we can understand that the LCM of 321,748,262,847,820 is 496503726180.
