Given numbers are 278,785,649,118
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,785,649,118 is 141631270.
Find LCM of 278,785,649,118 with Prime Factorization
| 2 | 278, 785, 649, 118 |
| 59 | 139, 785, 649, 59 |
| 139, 785, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 59 x 139 x 785 x 11 x 1 = 141631270
Therefore, the lowest common multiple of 278,785,649,118 is 141631270.
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 785 x 649 x 118 = 16712489860
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
785 : 1, 5, 157, 785
649 : 1, 11, 59, 649
118 : 1, 2, 59, 118
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,785,649,118, is 1.
Now, the common factors can be found like this.
278:2x 139
785:5x 157
649:11x 59
118:2x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 59 = 118
Therefore, the value for common factors is 118.
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 = 16712489860/(1x118)
LCM = 16712489860/118
LCM = 141631270
Thus, we can understand that the LCM of 278,785,649,118 is 141631270.
