Given numbers are 140,931,294,973,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,931,294,973,489 is 1265620020.
Find LCM of 140,931,294,973,489 with Prime Factorization
| 2 | 140, 931, 294, 973, 489 |
| 3 | 70, 931, 147, 973, 489 |
| 7 | 70, 931, 49, 973, 163 |
| 7 | 10, 133, 7, 139, 163 |
| 10, 19, 1, 139, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 10 x 19 x 1 x 139 x 163 = 1265620020
Therefore, the lowest common multiple of 140,931,294,973,489 is 1265620020.
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 931 x 294 x 973 x 489 = 18232522008120
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
931 : 1, 7, 19, 49, 133, 931
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
973 : 1, 7, 139, 973
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,931,294,973,489, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
931:7x 7x 19
294:2x 3x 7x 7
973:7x 139
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 7x 7x 7 = 14406
Therefore, the value for common factors is 14406.
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 = 18232522008120/(1x14406)
LCM = 18232522008120/14406
LCM = 1265620020
Thus, we can understand that the LCM of 140,931,294,973,489 is 1265620020.
