Given numbers are 844,748,847,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,748,847,220 is 60763780.
Find LCM of 844,748,847,220 with Prime Factorization
| 2 | 844, 748, 847, 220 |
| 2 | 422, 374, 847, 110 |
| 11 | 211, 187, 847, 55 |
| 211, 17, 77, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 211 x 17 x 77 x 5 = 60763780
Therefore, the lowest common multiple of 844,748,847,220 is 60763780.
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.
844 x 748 x 847 x 220 = 117638678080
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.
844 : 1, 2, 4, 211, 422, 844
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
847 : 1, 7, 11, 77, 121, 847
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,748,847,220, is 1.
Now, the common factors can be found like this.
844:2x 2x 211
748:2x 2x 11x 17
847:7x 11x 11
220:2x 2x 5x 11
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 2x 11x 11 = 1936
Therefore, the value for common factors is 1936.
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 = 117638678080/(1x1936)
LCM = 117638678080/1936
LCM = 60763780
Thus, we can understand that the LCM of 844,748,847,220 is 60763780.
