Given numbers are 617,494,620,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 617,494,620,836 is 1039361180.
Find LCM of 617,494,620,836 with Prime Factorization
| 2 | 617, 494, 620, 836 |
| 2 | 617, 247, 310, 418 |
| 19 | 617, 247, 155, 209 |
| 617, 13, 155, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 617 x 13 x 155 x 11 = 1039361180
Therefore, the lowest common multiple of 617,494,620,836 is 1039361180.
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.
617 x 494 x 620 x 836 = 157982899360
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.
617 : 1, 617
494 : 1, 2, 13, 19, 26, 38, 247, 494
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,494,620,836, is 1.
Now, the common factors can be found like this.
617:617
494:2x 13x 19
620:2x 2x 5x 31
836:2x 2x 11x 19
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 19 = 152
Therefore, the value for common factors is 152.
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 = 157982899360/(1x152)
LCM = 157982899360/152
LCM = 1039361180
Thus, we can understand that the LCM of 617,494,620,836 is 1039361180.
