Given numbers are 669,690,740,966
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,690,740,966 is 79704660.
Find LCM of 669,690,740,966 with Prime Factorization
| 2 | 669, 690, 740, 966 |
| 3 | 669, 345, 370, 483 |
| 5 | 223, 115, 370, 161 |
| 23 | 223, 23, 74, 161 |
| 223, 1, 74, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 223 x 1 x 74 x 7 = 79704660
Therefore, the lowest common multiple of 669,690,740,966 is 79704660.
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 690 x 740 x 966 = 329977292400
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
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,690,740,966, is 1.
Now, the common factors can be found like this.
669:3x 223
690:2x 3x 5x 23
740:2x 2x 5x 37
966:2x 3x 7x 23
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 3x 3x 5x 23 = 4140
Therefore, the value for common factors is 4140.
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 = 329977292400/(1x4140)
LCM = 329977292400/4140
LCM = 79704660
Thus, we can understand that the LCM of 669,690,740,966 is 79704660.
