Given numbers are 654,634,551,978,534
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 654,634,551,978,534 is 1657166786526.
Find LCM of 654,634,551,978,534 with Prime Factorization
| 2 | 654, 634, 551, 978, 534 |
| 3 | 327, 317, 551, 489, 267 |
| 109, 317, 551, 163, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 109 x 317 x 551 x 163 x 89 = 1657166786526
Therefore, the lowest common multiple of 654,634,551,978,534 is 1657166786526.
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.
654 x 634 x 551 x 978 x 534 = 119316008629872
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
634 : 1, 2, 317, 634
551 : 1, 19, 29, 551
978 : 1, 2, 3, 6, 163, 326, 489, 978
534 : 1, 2, 3, 6, 89, 178, 267, 534
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,634,551,978,534, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
634:2x 317
551:19x 29
978:2x 3x 163
534:2x 3x 89
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 3 = 72
Therefore, the value for common factors is 72.
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 = 119316008629872/(1x72)
LCM = 119316008629872/72
LCM = 1657166786526
Thus, we can understand that the LCM of 654,634,551,978,534 is 1657166786526.
