Given numbers are 781,897,708,118
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,897,708,118 is 165331452.
Find LCM of 781,897,708,118 with Prime Factorization
| 2 | 781, 897, 708, 118 |
| 3 | 781, 897, 354, 59 |
| 59 | 781, 299, 118, 59 |
| 781, 299, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 59 x 781 x 299 x 2 x 1 = 165331452
Therefore, the lowest common multiple of 781,897,708,118 is 165331452.
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 897 x 708 x 118 = 58527334008
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
897 : 1, 3, 13, 23, 39, 69, 299, 897
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
118 : 1, 2, 59, 118
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,897,708,118, is 1.
Now, the common factors can be found like this.
781:11x 71
897:3x 13x 23
708:2x 2x 3x 59
118:2x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 59 = 354
Therefore, the value for common factors is 354.
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 = 58527334008/(1x354)
LCM = 58527334008/354
LCM = 165331452
Thus, we can understand that the LCM of 781,897,708,118 is 165331452.
