Given numbers are 488,247,772,942,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 488,247,772,942,642 is 1172407988856.
Find LCM of 488,247,772,942,642 with Prime Factorization
| 2 | 488, 247, 772, 942, 642 |
| 2 | 244, 247, 386, 471, 321 |
| 3 | 122, 247, 193, 471, 321 |
| 122, 247, 193, 157, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 122 x 247 x 193 x 157 x 107 = 1172407988856
Therefore, the lowest common multiple of 488,247,772,942,642 is 1172407988856.
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.
488 x 247 x 772 x 942 x 642 = 56275583465088
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.
488 : 1, 2, 4, 8, 61, 122, 244, 488
247 : 1, 13, 19, 247
772 : 1, 2, 4, 193, 386, 772
942 : 1, 2, 3, 6, 157, 314, 471, 942
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 488,247,772,942,642, is 1.
Now, the common factors can be found like this.
488:2x 2x 2x 61
247:13x 19
772:2x 2x 193
942:2x 3x 157
642:2x 3x 107
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 3 = 48
Therefore, the value for common factors is 48.
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 = 56275583465088/(1x48)
LCM = 56275583465088/48
LCM = 1172407988856
Thus, we can understand that the LCM of 488,247,772,942,642 is 1172407988856.
