Given numbers are 834,497,280,564,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,497,280,564,221 is 86107814520.
Find LCM of 834,497,280,564,221 with Prime Factorization
| 2 | 834, 497, 280, 564, 221 |
| 2 | 417, 497, 140, 282, 221 |
| 3 | 417, 497, 70, 141, 221 |
| 7 | 139, 497, 70, 47, 221 |
| 139, 71, 10, 47, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 139 x 71 x 10 x 47 x 221 = 86107814520
Therefore, the lowest common multiple of 834,497,280,564,221 is 86107814520.
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.
834 x 497 x 280 x 564 x 221 = 14466112839360
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
497 : 1, 7, 71, 497
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,497,280,564,221, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
497:7x 71
280:2x 2x 2x 5x 7
564:2x 2x 3x 47
221:13x 17
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 7 = 168
Therefore, the value for common factors is 168.
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 = 14466112839360/(1x168)
LCM = 14466112839360/168
LCM = 86107814520
Thus, we can understand that the LCM of 834,497,280,564,221 is 86107814520.
