The LCM of 674,780,483,644 is 42320460.
Find LCM of 674,780,483,644 with Prime Factorization
| 2 | 674, 780, 483, 644 |
| 2 | 337, 390, 483, 322 |
| 3 | 337, 195, 483, 161 |
| 7 | 337, 65, 161, 161 |
| 23 | 337, 65, 23, 23 |
| 337, 65, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 23 x 337 x 65 x 1 x 1 = 42320460
Therefore, the lowest common multiple of 674,780,483,644 is 42320460.
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.
674 x 780 x 483 x 644 = 163526257440
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.
674 : 1, 2, 337, 674
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
483 : 1, 3, 7, 21, 23, 69, 161, 483
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,780,483,644, is 1.
Now, the common factors can be found like this.
674:2x 337
780:2x 2x 3x 5x 13
483:3x 7x 23
644:2x 2x 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 2x 3x 7x 23 = 3864
Therefore, the value for common factors is 3864.
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 = 163526257440/(1x3864)
LCM = 163526257440/3864
LCM = 42320460
Thus, we can understand that the LCM of 674,780,483,644 is 42320460.
