Given numbers are 720,884,894,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,884,894,754 is 687557520.
Find LCM of 720,884,894,754 with Prime Factorization
| 2 | 720, 884, 894, 754 |
| 2 | 360, 442, 447, 377 |
| 3 | 180, 221, 447, 377 |
| 13 | 60, 221, 149, 377 |
| 60, 17, 149, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 60 x 17 x 149 x 29 = 687557520
Therefore, the lowest common multiple of 720,884,894,754 is 687557520.
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.
720 x 884 x 894 x 754 = 429035892480
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
894 : 1, 2, 3, 6, 149, 298, 447, 894
754 : 1, 2, 13, 26, 29, 58, 377, 754
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,884,894,754, is 2.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
884:2x 2x 13x 17
894:2x 3x 149
754:2x 13x 29
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 13 = 312
Therefore, the value for common factors is 312.
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 = 429035892480/(2x312)
LCM = 429035892480/624
LCM = 687557520
Thus, we can understand that the LCM of 720,884,894,754 is 687557520.
