Find LCM of 980,605,624,897,961 with Prime Factorization
| 2 | 980, 605, 624, 897, 961 |
| 2 | 490, 605, 312, 897, 961 |
| 3 | 245, 605, 156, 897, 961 |
| 5 | 245, 605, 52, 299, 961 |
| 13 | 49, 121, 52, 299, 961 |
| 49, 121, 4, 23, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 49 x 121 x 4 x 23 x 961 = 408871903440
Therefore, the lowest common multiple of 980,605,624,897,961 is 408871903440.
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.
980 x 605 x 624 x 897 x 961 = 318920084683200
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
605 : 1, 5, 11, 55, 121, 605
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
897 : 1, 3, 13, 23, 39, 69, 299, 897
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,605,624,897,961, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
605:5x 11x 11
624:2x 2x 2x 2x 3x 13
897:3x 13x 23
961:31x 31
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 3x 5x 13 = 780
Therefore, the value for common factors is 780.
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 = 318920084683200/(1x780)
LCM = 318920084683200/780
LCM = 408871903440
Thus, we can understand that the LCM of 980,605,624,897,961 is 408871903440.
