Given numbers are 690,554,905,201,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,554,905,201,380 is 88077673380.
Find LCM of 690,554,905,201,380 with Prime Factorization
| 2 | 690, 554, 905, 201, 380 |
| 3 | 345, 277, 905, 201, 190 |
| 5 | 115, 277, 905, 67, 190 |
| 23, 277, 181, 67, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 277 x 181 x 67 x 38 = 88077673380
Therefore, the lowest common multiple of 690,554,905,201,380 is 88077673380.
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.
690 x 554 x 905 x 201 x 380 = 26423302014000
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
554 : 1, 2, 277, 554
905 : 1, 5, 181, 905
201 : 1, 3, 67, 201
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,554,905,201,380, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
554:2x 277
905:5x 181
201:3x 67
380:2x 2x 5x 19
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 26423302014000/(1x300)
LCM = 26423302014000/300
LCM = 88077673380
Thus, we can understand that the LCM of 690,554,905,201,380 is 88077673380.
