Given numbers are 646,676,961,416,725
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,676,961,416,725 is 1217028082400.
Find LCM of 646,676,961,416,725 with Prime Factorization
2 | 646, 676, 961, 416, 725 |
2 | 323, 338, 961, 208, 725 |
13 | 323, 169, 961, 104, 725 |
323, 13, 961, 8, 725 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 323 x 13 x 961 x 8 x 725 = 1217028082400
Therefore, the lowest common multiple of 646,676,961,416,725 is 1217028082400.
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.
646 x 676 x 961 x 416 x 725 = 126570920569600
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
961 : 1, 31, 961
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
725 : 1, 5, 25, 29, 145, 725
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,676,961,416,725, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
676:2x 2x 13x 13
961:31x 31
416:2x 2x 2x 2x 2x 13
725:5x 5x 29
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 13 = 104
Therefore, the value for common factors is 104.
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 = 126570920569600/(1x104)
LCM = 126570920569600/104
LCM = 1217028082400
Thus, we can understand that the LCM of 646,676,961,416,725 is 1217028082400.
