The LCM of 425,876,980,791 is 2061425100.
Find LCM of 425,876,980,791 with Prime Factorization
| 2 | 425, 876, 980, 791 |
| 2 | 425, 438, 490, 791 |
| 5 | 425, 219, 245, 791 |
| 7 | 85, 219, 49, 791 |
| 85, 219, 7, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 85 x 219 x 7 x 113 = 2061425100
Therefore, the lowest common multiple of 425,876,980,791 is 2061425100.
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.
425 x 876 x 980 x 791 = 288599514000
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.
425 : 1, 5, 17, 25, 85, 425
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 425,876,980,791, is 1.
Now, the common factors can be found like this.
425:5x 5x 17
876:2x 2x 3x 73
980:2x 2x 5x 7x 7
791:7x 113
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 288599514000/(1x140)
LCM = 288599514000/140
LCM = 2061425100
Thus, we can understand that the LCM of 425,876,980,791 is 2061425100.
