Given numbers are 894,405,142,734,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 894,405,142,734,690 is 72330844590.
Find LCM of 894,405,142,734,690 with Prime Factorization
| 2 | 894, 405, 142, 734, 690 |
| 3 | 447, 405, 71, 367, 345 |
| 5 | 149, 135, 71, 367, 115 |
| 149, 27, 71, 367, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 149 x 27 x 71 x 367 x 23 = 72330844590
Therefore, the lowest common multiple of 894,405,142,734,690 is 72330844590.
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.
894 x 405 x 142 x 734 x 690 = 26039104052400
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.
894 : 1, 2, 3, 6, 149, 298, 447, 894
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
142 : 1, 2, 71, 142
734 : 1, 2, 367, 734
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,405,142,734,690, is 1.
Now, the common factors can be found like this.
894:2x 3x 149
405:3x 3x 3x 3x 5
142:2x 71
734:2x 367
690:2x 3x 5x 23
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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 26039104052400/(1x360)
LCM = 26039104052400/360
LCM = 72330844590
Thus, we can understand that the LCM of 894,405,142,734,690 is 72330844590.
