Given numbers are 850,387,408,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 850,387,408,980 is 64474200.
Find LCM of 850,387,408,980 with Prime Factorization
| 2 | 850, 387, 408, 980 |
| 2 | 425, 387, 204, 490 |
| 3 | 425, 387, 102, 245 |
| 5 | 425, 129, 34, 245 |
| 17 | 85, 129, 34, 49 |
| 5, 129, 2, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 5 x 129 x 2 x 49 = 64474200
Therefore, the lowest common multiple of 850,387,408,980 is 64474200.
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.
850 x 387 x 408 x 980 = 131527368000
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.
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
387 : 1, 3, 9, 43, 129, 387
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 850,387,408,980, is 1.
Now, the common factors can be found like this.
850:2x 5x 5x 17
387:3x 3x 43
408:2x 2x 2x 3x 17
980:2x 2x 5x 7x 7
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 5x 17 = 2040
Therefore, the value for common factors is 2040.
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 = 131527368000/(1x2040)
LCM = 131527368000/2040
LCM = 64474200
Thus, we can understand that the LCM of 850,387,408,980 is 64474200.
