Given numbers are 791,154,658,286,617
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,154,658,286,617 is 6560327774.
Find LCM of 791,154,658,286,617 with Prime Factorization
| 2 | 791, 154, 658, 286, 617 |
| 7 | 791, 77, 329, 143, 617 |
| 11 | 113, 11, 47, 143, 617 |
| 113, 1, 47, 13, 617 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 113 x 1 x 47 x 13 x 617 = 6560327774
Therefore, the lowest common multiple of 791,154,658,286,617 is 6560327774.
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.
791 x 154 x 658 x 286 x 617 = 14144066680744
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.
791 : 1, 7, 113, 791
154 : 1, 2, 7, 11, 14, 22, 77, 154
658 : 1, 2, 7, 14, 47, 94, 329, 658
286 : 1, 2, 11, 13, 22, 26, 143, 286
617 : 1, 617
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,154,658,286,617, is 1.
Now, the common factors can be found like this.
791:7x 113
154:2x 7x 11
658:2x 7x 47
286:2x 11x 13
617:617
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 7x 7x 11 = 2156
Therefore, the value for common factors is 2156.
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 = 14144066680744/(1x2156)
LCM = 14144066680744/2156
LCM = 6560327774
Thus, we can understand that the LCM of 791,154,658,286,617 is 6560327774.
