Given numbers are 781,572,626,873,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,572,626,873,308 is 77680318716.
Find LCM of 781,572,626,873,308 with Prime Factorization
| 2 | 781, 572, 626, 873, 308 |
| 2 | 781, 286, 313, 873, 154 |
| 11 | 781, 143, 313, 873, 77 |
| 71, 13, 313, 873, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 71 x 13 x 313 x 873 x 7 = 77680318716
Therefore, the lowest common multiple of 781,572,626,873,308 is 77680318716.
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.
781 x 572 x 626 x 873 x 308 = 75194548517088
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.
781 : 1, 11, 71, 781
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
626 : 1, 2, 313, 626
873 : 1, 3, 9, 97, 291, 873
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,572,626,873,308, is 1.
Now, the common factors can be found like this.
781:11x 71
572:2x 2x 11x 13
626:2x 313
873:3x 3x 97
308:2x 2x 7x 11
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 11x 11 = 968
Therefore, the value for common factors is 968.
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 = 75194548517088/(1x968)
LCM = 75194548517088/968
LCM = 77680318716
Thus, we can understand that the LCM of 781,572,626,873,308 is 77680318716.
