Given numbers are 807,708,791,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 807,708,791,781 is 117655722492.
Find LCM of 807,708,791,781 with Prime Factorization
| 3 | 807, 708, 791, 781 |
| 269, 236, 791, 781 |
Multiply the prime numbers at the bottom and the left side.
3 x 269 x 236 x 791 x 781 = 117655722492
Therefore, the lowest common multiple of 807,708,791,781 is 117655722492.
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.
807 x 708 x 791 x 781 = 352967167476
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.
807 : 1, 3, 269, 807
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
791 : 1, 7, 113, 791
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,708,791,781, is 1.
Now, the common factors can be found like this.
807:3x 269
708:2x 2x 3x 59
791:7x 113
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 352967167476/(1x3)
LCM = 352967167476/3
LCM = 117655722492
Thus, we can understand that the LCM of 807,708,791,781 is 117655722492.
