Given numbers are 7,610,340,854
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,610,340,854 is 145180.
Find LCM of 7,610,340,854 with Prime Factorization
| 2 | 7, 610, 340, 854 |
| 5 | 7, 305, 170, 427 |
| 7 | 7, 61, 34, 427 |
| 61 | 1, 61, 34, 61 |
| 1, 1, 34, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 61 x 1 x 1 x 34 x 1 = 145180
Therefore, the lowest common multiple of 7,610,340,854 is 145180.
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.
7 x 610 x 340 x 854 = 1239837200
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.
7 : 1, 7
610 : 1, 2, 5, 10, 61, 122, 305, 610
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
854 : 1, 2, 7, 14, 61, 122, 427, 854
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,610,340,854, is 1.
Now, the common factors can be found like this.
7:7
610:2x 5x 61
340:2x 2x 5x 17
854:2x 7x 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 5x 7x 61 = 8540
Therefore, the value for common factors is 8540.
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 = 1239837200/(1x8540)
LCM = 1239837200/8540
LCM = 145180
Thus, we can understand that the LCM of 7,610,340,854 is 145180.
