Given numbers are 278,990,970,823,744
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,990,970,823,744 is 1362207444840.
Find LCM of 278,990,970,823,744 with Prime Factorization
| 2 | 278, 990, 970, 823, 744 |
| 3 | 139, 495, 485, 823, 372 |
| 5 | 139, 165, 485, 823, 124 |
| 139, 33, 97, 823, 124 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 139 x 33 x 97 x 823 x 124 = 1362207444840
Therefore, the lowest common multiple of 278,990,970,823,744 is 1362207444840.
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 990 x 970 x 823 x 744 = 163464893380800
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
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
970 : 1, 2, 5, 10, 97, 194, 485, 970
823 : 1, 823
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,990,970,823,744, is 1.
Now, the common factors can be found like this.
278:2x 139
990:2x 3x 3x 5x 11
970:2x 5x 97
823:823
744:2x 2x 2x 3x 31
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 163464893380800/(1x120)
LCM = 163464893380800/120
LCM = 1362207444840
Thus, we can understand that the LCM of 278,990,970,823,744 is 1362207444840.
