Given numbers are 492,432,407,254
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 492,432,407,254 is 915515568.
Find LCM of 492,432,407,254 with Prime Factorization
| 2 | 492, 432, 407, 254 |
| 2 | 246, 216, 407, 127 |
| 3 | 123, 108, 407, 127 |
| 41, 36, 407, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 41 x 36 x 407 x 127 = 915515568
Therefore, the lowest common multiple of 492,432,407,254 is 915515568.
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.
492 x 432 x 407 x 254 = 21972373632
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.
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
407 : 1, 11, 37, 407
254 : 1, 2, 127, 254
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,432,407,254, is 1.
Now, the common factors can be found like this.
492:2x 2x 3x 41
432:2x 2x 2x 2x 3x 3x 3
407:11x 37
254:2x 127
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 3 = 24
Therefore, the value for common factors is 24.
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 = 21972373632/(1x24)
LCM = 21972373632/24
LCM = 915515568
Thus, we can understand that the LCM of 492,432,407,254 is 915515568.
