Given numbers are 969,128,776,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,128,776,685 is 8241306240.
Find LCM of 969,128,776,685 with Prime Factorization
2 | 969, 128, 776, 685 |
2 | 969, 64, 388, 685 |
2 | 969, 32, 194, 685 |
969, 16, 97, 685 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 969 x 16 x 97 x 685 = 8241306240
Therefore, the lowest common multiple of 969,128,776,685 is 8241306240.
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.
969 x 128 x 776 x 685 = 65930449920
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
128 : 1, 2, 4, 8, 16, 32, 64, 128
776 : 1, 2, 4, 8, 97, 194, 388, 776
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,128,776,685, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
128:2x 2x 2x 2x 2x 2x 2
776:2x 2x 2x 97
685:5x 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 2x 2 = 8
Therefore, the value for common factors is 8.
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 = 65930449920/(1x8)
LCM = 65930449920/8
LCM = 8241306240
Thus, we can understand that the LCM of 969,128,776,685 is 8241306240.
