Given numbers are 140,854,445,558
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,854,445,558 is 212056740.
Find LCM of 140,854,445,558 with Prime Factorization
| 2 | 140, 854, 445, 558 |
| 5 | 70, 427, 445, 279 |
| 7 | 14, 427, 89, 279 |
| 2, 61, 89, 279 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 2 x 61 x 89 x 279 = 212056740
Therefore, the lowest common multiple of 140,854,445,558 is 212056740.
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.
140 x 854 x 445 x 558 = 29687943600
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
854 : 1, 2, 7, 14, 61, 122, 427, 854
445 : 1, 5, 89, 445
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,854,445,558, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
854:2x 7x 61
445:5x 89
558:2x 3x 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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 29687943600/(1x140)
LCM = 29687943600/140
LCM = 212056740
Thus, we can understand that the LCM of 140,854,445,558 is 212056740.
