Find LCM of 781,889,816,678,959 with Prime Factorization
2 | 781, 889, 816, 678, 959 |
3 | 781, 889, 408, 339, 959 |
7 | 781, 889, 136, 113, 959 |
781, 127, 136, 113, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 781 x 127 x 136 x 113 x 137 = 8770855665264
Therefore, the lowest common multiple of 781,889,816,678,959 is 8770855665264.
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 889 x 816 x 678 x 959 = 368375937941088
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
889 : 1, 7, 127, 889
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
678 : 1, 2, 3, 6, 113, 226, 339, 678
959 : 1, 7, 137, 959
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,889,816,678,959, is 1.
Now, the common factors can be found like this.
781:11x 71
889:7x 127
816:2x 2x 2x 2x 3x 17
678:2x 3x 113
959:7x 137
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 7 = 42
Therefore, the value for common factors is 42.
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 = 368375937941088/(1x42)
LCM = 368375937941088/42
LCM = 8770855665264
Thus, we can understand that the LCM of 781,889,816,678,959 is 8770855665264.
