Given numbers are 769,169,854,942,912
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 769,169,854,942,912 is 7945759396848.
Find LCM of 769,169,854,942,912 with Prime Factorization
| 2 | 769, 169, 854, 942, 912 |
| 3 | 769, 169, 427, 471, 456 |
| 769, 169, 427, 157, 152 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 769 x 169 x 427 x 157 x 152 = 7945759396848
Therefore, the lowest common multiple of 769,169,854,942,912 is 7945759396848.
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.
769 x 169 x 854 x 942 x 912 = 95349112762176
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.
769 : 1, 769
169 : 1, 13, 169
854 : 1, 2, 7, 14, 61, 122, 427, 854
942 : 1, 2, 3, 6, 157, 314, 471, 942
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,169,854,942,912, is 1.
Now, the common factors can be found like this.
769:769
169:13x 13
854:2x 7x 61
942:2x 3x 157
912:2x 2x 2x 2x 3x 19
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 3 = 12
Therefore, the value for common factors is 12.
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 = 95349112762176/(1x12)
LCM = 95349112762176/12
LCM = 7945759396848
Thus, we can understand that the LCM of 769,169,854,942,912 is 7945759396848.
