Given numbers are 376,987,556,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 376,987,556,520 is 71340360.
Find LCM of 376,987,556,520 with Prime Factorization
| 2 | 376, 987, 556, 520 |
| 2 | 188, 987, 278, 260 |
| 2 | 94, 987, 139, 130 |
| 47 | 47, 987, 139, 65 |
| 1, 21, 139, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 47 x 1 x 21 x 139 x 65 = 71340360
Therefore, the lowest common multiple of 376,987,556,520 is 71340360.
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.
376 x 987 x 556 x 520 = 107295901440
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.
376 : 1, 2, 4, 8, 47, 94, 188, 376
987 : 1, 3, 7, 21, 47, 141, 329, 987
556 : 1, 2, 4, 139, 278, 556
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 376,987,556,520, is 1.
Now, the common factors can be found like this.
376:2x 2x 2x 47
987:3x 7x 47
556:2x 2x 139
520:2x 2x 2x 5x 13
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 2x 2x 47 = 1504
Therefore, the value for common factors is 1504.
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 = 107295901440/(1x1504)
LCM = 107295901440/1504
LCM = 71340360
Thus, we can understand that the LCM of 376,987,556,520 is 71340360.
