Given numbers are 753,442,978,191,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 753,442,978,191,816 is 82894974864.
Find LCM of 753,442,978,191,816 with Prime Factorization
| 2 | 753, 442, 978, 191, 816 |
| 3 | 753, 221, 489, 191, 408 |
| 17 | 251, 221, 163, 191, 136 |
| 251, 13, 163, 191, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 251 x 13 x 163 x 191 x 8 = 82894974864
Therefore, the lowest common multiple of 753,442,978,191,816 is 82894974864.
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.
753 x 442 x 978 x 191 x 816 = 50731724616768
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.
753 : 1, 3, 251, 753
442 : 1, 2, 13, 17, 26, 34, 221, 442
978 : 1, 2, 3, 6, 163, 326, 489, 978
191 : 1, 191
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 753,442,978,191,816, is 1.
Now, the common factors can be found like this.
753:3x 251
442:2x 13x 17
978:2x 3x 163
191:191
816:2x 2x 2x 2x 3x 17
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 3x 3x 17 = 612
Therefore, the value for common factors is 612.
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 = 50731724616768/(1x612)
LCM = 50731724616768/612
LCM = 82894974864
Thus, we can understand that the LCM of 753,442,978,191,816 is 82894974864.
