Given numbers are 278,292,771,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,292,771,961 is 30072907428.
Find LCM of 278,292,771,961 with Prime Factorization
| 2 | 278, 292, 771, 961 |
| 139, 146, 771, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 146 x 771 x 961 = 30072907428
Therefore, the lowest common multiple of 278,292,771,961 is 30072907428.
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.
278 x 292 x 771 x 961 = 60145814856
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.
278 : 1, 2, 139, 278
292 : 1, 2, 4, 73, 146, 292
771 : 1, 3, 257, 771
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,292,771,961, is 1.
Now, the common factors can be found like this.
278:2x 139
292:2x 2x 73
771:3x 257
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 60145814856/(1x2)
LCM = 60145814856/2
LCM = 30072907428
Thus, we can understand that the LCM of 278,292,771,961 is 30072907428.
