Given numbers are 862,723,702
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 862,723,702 is 72917442.
Find LCM of 862,723,702 with Prime Factorization
| 2 | 862, 723, 702 |
| 3 | 431, 723, 351 |
| 431, 241, 117 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 431 x 241 x 117 = 72917442
Therefore, the lowest common multiple of 862,723,702 is 72917442.
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.
862 x 723 x 702 = 437504652
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.
862 : 1, 2, 431, 862
723 : 1, 3, 241, 723
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,723,702, is 1.
Now, the common factors can be found like this.
862:2x 431
723:3x 241
702:2x 3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 437504652/(1x6)
LCM = 437504652/6
LCM = 72917442
Thus, we can understand that the LCM of 862,723,702 is 72917442.
