Given numbers are 684,221,551,706,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,221,551,706,902 is 697907106468.
Find LCM of 684,221,551,706,902 with Prime Factorization
| 2 | 684, 221, 551, 706, 902 |
| 19 | 342, 221, 551, 353, 451 |
| 18, 221, 29, 353, 451 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 18 x 221 x 29 x 353 x 451 = 697907106468
Therefore, the lowest common multiple of 684,221,551,706,902 is 697907106468.
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.
684 x 221 x 551 x 706 x 902 = 53040940091568
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
221 : 1, 13, 17, 221
551 : 1, 19, 29, 551
706 : 1, 2, 353, 706
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,221,551,706,902, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
221:13x 17
551:19x 29
706:2x 353
902:2x 11x 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 19 = 76
Therefore, the value for common factors is 76.
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 = 53040940091568/(1x76)
LCM = 53040940091568/76
LCM = 697907106468
Thus, we can understand that the LCM of 684,221,551,706,902 is 697907106468.
