Given numbers are 487,478,478,492
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,478,478,492 is 57265356.
Find LCM of 487,478,478,492 with Prime Factorization
2 | 487, 478, 478, 492 |
239 | 487, 239, 239, 246 |
487, 1, 1, 246 |
Multiply the prime numbers at the bottom and the left side.
2 x 239 x 487 x 1 x 1 x 246 = 57265356
Therefore, the lowest common multiple of 487,478,478,492 is 57265356.
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.
487 x 478 x 478 x 492 = 54745680336
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.
487 : 1, 487
478 : 1, 2, 239, 478
478 : 1, 2, 239, 478
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,478,478,492, is 1.
Now, the common factors can be found like this.
487:487
478:2x 239
478:2x 239
492:2x 2x 3x 41
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 239 = 956
Therefore, the value for common factors is 956.
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 = 54745680336/(1x956)
LCM = 54745680336/956
LCM = 57265356
Thus, we can understand that the LCM of 487,478,478,492 is 57265356.
