Given numbers are 392,662,542
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,662,542 is 35162792.
Find LCM of 392,662,542 with Prime Factorization
| 2 | 392, 662, 542 |
| 196, 331, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 196 x 331 x 271 = 35162792
Therefore, the lowest common multiple of 392,662,542 is 35162792.
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.
392 x 662 x 542 = 140651168
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
662 : 1, 2, 331, 662
542 : 1, 2, 271, 542
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,662,542, is 2.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
662:2x 331
542:2x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 140651168/(2x2)
LCM = 140651168/4
LCM = 35162792
Thus, we can understand that the LCM of 392,662,542 is 35162792.
