Given numbers are 358,520,649,488
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 358,520,649,488 is 3684944120.
Find LCM of 358,520,649,488 with Prime Factorization
| 2 | 358, 520, 649, 488 |
| 2 | 179, 260, 649, 244 |
| 2 | 179, 130, 649, 122 |
| 179, 65, 649, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 179 x 65 x 649 x 61 = 3684944120
Therefore, the lowest common multiple of 358,520,649,488 is 3684944120.
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.
358 x 520 x 649 x 488 = 58959105920
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.
358 : 1, 2, 179, 358
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
649 : 1, 11, 59, 649
488 : 1, 2, 4, 8, 61, 122, 244, 488
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 358,520,649,488, is 1.
Now, the common factors can be found like this.
358:2x 179
520:2x 2x 2x 5x 13
649:11x 59
488:2x 2x 2x 61
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 2 = 16
Therefore, the value for common factors is 16.
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 = 58959105920/(1x16)
LCM = 58959105920/16
LCM = 3684944120
Thus, we can understand that the LCM of 358,520,649,488 is 3684944120.
