Given numbers are 217,763,944,686,916
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 217,763,944,686,916 is 250547335472.
Find LCM of 217,763,944,686,916 with Prime Factorization
| 2 | 217, 763, 944, 686, 916 |
| 2 | 217, 763, 472, 343, 458 |
| 7 | 217, 763, 236, 343, 229 |
| 31, 109, 236, 49, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 31 x 109 x 236 x 49 x 229 = 250547335472
Therefore, the lowest common multiple of 217,763,944,686,916 is 250547335472.
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.
217 x 763 x 944 x 686 x 916 = 98214555505024
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.
217 : 1, 7, 31, 217
763 : 1, 7, 109, 763
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
686 : 1, 2, 7, 14, 49, 98, 343, 686
916 : 1, 2, 4, 229, 458, 916
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,763,944,686,916, is 1.
Now, the common factors can be found like this.
217:7x 31
763:7x 109
944:2x 2x 2x 2x 59
686:2x 7x 7x 7
916:2x 2x 229
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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 98214555505024/(1x392)
LCM = 98214555505024/392
LCM = 250547335472
Thus, we can understand that the LCM of 217,763,944,686,916 is 250547335472.
