Given numbers are 957,438,609,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 957,438,609,655 is 640625370.
Find LCM of 957,438,609,655 with Prime Factorization
3 | 957, 438, 609, 655 |
29 | 319, 146, 203, 655 |
11, 146, 7, 655 |
Multiply the prime numbers at the bottom and the left side.
3 x 29 x 11 x 146 x 7 x 655 = 640625370
Therefore, the lowest common multiple of 957,438,609,655 is 640625370.
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.
957 x 438 x 609 x 655 = 167203221570
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.
957 : 1, 3, 11, 29, 33, 87, 319, 957
438 : 1, 2, 3, 6, 73, 146, 219, 438
609 : 1, 3, 7, 21, 29, 87, 203, 609
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,438,609,655, is 1.
Now, the common factors can be found like this.
957:3x 11x 29
438:2x 3x 73
609:3x 7x 29
655:5x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 29 = 261
Therefore, the value for common factors is 261.
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 = 167203221570/(1x261)
LCM = 167203221570/261
LCM = 640625370
Thus, we can understand that the LCM of 957,438,609,655 is 640625370.
