Given numbers are 882,292,722,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 882,292,722,420 is 232433460.
Find LCM of 882,292,722,420 with Prime Factorization
| 2 | 882, 292, 722, 420 |
| 2 | 441, 146, 361, 210 |
| 3 | 441, 73, 361, 105 |
| 7 | 147, 73, 361, 35 |
| 21, 73, 361, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 21 x 73 x 361 x 5 = 232433460
Therefore, the lowest common multiple of 882,292,722,420 is 232433460.
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.
882 x 292 x 722 x 420 = 78097642560
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.
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
292 : 1, 2, 4, 73, 146, 292
722 : 1, 2, 19, 38, 361, 722
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,292,722,420, is 2.
Now, the common factors can be found like this.
882:2x 3x 3x 7x 7
292:2x 2x 73
722:2x 19x 19
420:2x 2x 3x 5x 7
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 7 = 168
Therefore, the value for common factors is 168.
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 = 78097642560/(2x168)
LCM = 78097642560/336
LCM = 232433460
Thus, we can understand that the LCM of 882,292,722,420 is 232433460.
