Given numbers are 461,648,316,862,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 461,648,316,862,978 is 1657936516536.
Find LCM of 461,648,316,862,978 with Prime Factorization
| 2 | 461, 648, 316, 862, 978 |
| 2 | 461, 324, 158, 431, 489 |
| 3 | 461, 162, 79, 431, 489 |
| 461, 54, 79, 431, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 461 x 54 x 79 x 431 x 163 = 1657936516536
Therefore, the lowest common multiple of 461,648,316,862,978 is 1657936516536.
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.
461 x 648 x 316 x 862 x 978 = 79580952793728
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.
461 : 1, 461
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
316 : 1, 2, 4, 79, 158, 316
862 : 1, 2, 431, 862
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 461,648,316,862,978, is 1.
Now, the common factors can be found like this.
461:461
648:2x 2x 2x 3x 3x 3x 3
316:2x 2x 79
862:2x 431
978:2x 3x 163
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 79580952793728/(1x48)
LCM = 79580952793728/48
LCM = 1657936516536
Thus, we can understand that the LCM of 461,648,316,862,978 is 1657936516536.
