Given numbers are 669,667,174,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,667,174,992 is 442653216.
Find LCM of 669,667,174,992 with Prime Factorization
| 2 | 669, 667, 174, 992 |
| 3 | 669, 667, 87, 496 |
| 29 | 223, 667, 29, 496 |
| 223, 23, 1, 496 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 223 x 23 x 1 x 496 = 442653216
Therefore, the lowest common multiple of 669,667,174,992 is 442653216.
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.
669 x 667 x 174 x 992 = 77021659584
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.
669 : 1, 3, 223, 669
667 : 1, 23, 29, 667
174 : 1, 2, 3, 6, 29, 58, 87, 174
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,667,174,992, is 1.
Now, the common factors can be found like this.
669:3x 223
667:23x 29
174:2x 3x 29
992:2x 2x 2x 2x 2x 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 3x 29 = 174
Therefore, the value for common factors is 174.
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 = 77021659584/(1x174)
LCM = 77021659584/174
LCM = 442653216
Thus, we can understand that the LCM of 669,667,174,992 is 442653216.
