Given numbers are 912,140,817,911
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 912,140,817,911 is 1250402160.
Find LCM of 912,140,817,911 with Prime Factorization
| 2 | 912, 140, 817, 911 |
| 2 | 456, 70, 817, 911 |
| 19 | 228, 35, 817, 911 |
| 12, 35, 43, 911 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 12 x 35 x 43 x 911 = 1250402160
Therefore, the lowest common multiple of 912,140,817,911 is 1250402160.
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.
912 x 140 x 817 x 911 = 95030564160
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
817 : 1, 19, 43, 817
911 : 1, 911
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,140,817,911, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
140:2x 2x 5x 7
817:19x 43
911:911
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 19 = 76
Therefore, the value for common factors is 76.
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 = 95030564160/(1x76)
LCM = 95030564160/76
LCM = 1250402160
Thus, we can understand that the LCM of 912,140,817,911 is 1250402160.
