Given numbers are 676,622,781,544,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,622,781,544,661 is 14760412231136.
Find LCM of 676,622,781,544,661 with Prime Factorization
| 2 | 676, 622, 781, 544, 661 |
| 2 | 338, 311, 781, 272, 661 |
| 169, 311, 781, 136, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 169 x 311 x 781 x 136 x 661 = 14760412231136
Therefore, the lowest common multiple of 676,622,781,544,661 is 14760412231136.
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.
676 x 622 x 781 x 544 x 661 = 118083297849088
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
622 : 1, 2, 311, 622
781 : 1, 11, 71, 781
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,622,781,544,661, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
622:2x 311
781:11x 71
544:2x 2x 2x 2x 2x 17
661:661
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 2 = 8
Therefore, the value for common factors is 8.
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 = 118083297849088/(1x8)
LCM = 118083297849088/8
LCM = 14760412231136
Thus, we can understand that the LCM of 676,622,781,544,661 is 14760412231136.
