Given numbers are 640,754,383,822
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,754,383,822 is 37980608640.
Find LCM of 640,754,383,822 with Prime Factorization
2 | 640, 754, 383, 822 |
320, 377, 383, 411 |
Multiply the prime numbers at the bottom and the left side.
2 x 320 x 377 x 383 x 411 = 37980608640
Therefore, the lowest common multiple of 640,754,383,822 is 37980608640.
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.
640 x 754 x 383 x 822 = 151922434560
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
754 : 1, 2, 13, 26, 29, 58, 377, 754
383 : 1, 383
822 : 1, 2, 3, 6, 137, 274, 411, 822
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,754,383,822, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
754:2x 13x 29
383:383
822:2x 3x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 151922434560/(1x4)
LCM = 151922434560/4
LCM = 37980608640
Thus, we can understand that the LCM of 640,754,383,822 is 37980608640.
