Given numbers are 669,770,407,198,984
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,770,407,198,984 is 9377426520.
Find LCM of 669,770,407,198,984 with Prime Factorization
| 2 | 669, 770, 407, 198, 984 |
| 3 | 669, 385, 407, 99, 492 |
| 11 | 223, 385, 407, 33, 164 |
| 223, 35, 37, 3, 164 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 223 x 35 x 37 x 3 x 164 = 9377426520
Therefore, the lowest common multiple of 669,770,407,198,984 is 9377426520.
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 770 x 407 x 198 x 984 = 40848069921120
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
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
407 : 1, 11, 37, 407
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,770,407,198,984, is 1.
Now, the common factors can be found like this.
669:3x 223
770:2x 5x 7x 11
407:11x 37
198:2x 3x 3x 11
984:2x 2x 2x 3x 41
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 11x 11 = 4356
Therefore, the value for common factors is 4356.
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 = 40848069921120/(1x4356)
LCM = 40848069921120/4356
LCM = 9377426520
Thus, we can understand that the LCM of 669,770,407,198,984 is 9377426520.
