Find LCM of 291,978,985,266,776 with Prime Factorization
2 | 291, 978, 985, 266, 776 |
3 | 291, 489, 985, 133, 388 |
97 | 97, 163, 985, 133, 388 |
1, 163, 985, 133, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 97 x 1 x 163 x 985 x 133 x 4 = 49711681320
Therefore, the lowest common multiple of 291,978,985,266,776 is 49711681320.
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.
291 x 978 x 985 x 266 x 776 = 57864397056480
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.
291 : 1, 3, 97, 291
978 : 1, 2, 3, 6, 163, 326, 489, 978
985 : 1, 5, 197, 985
266 : 1, 2, 7, 14, 19, 38, 133, 266
776 : 1, 2, 4, 8, 97, 194, 388, 776
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,978,985,266,776, is 1.
Now, the common factors can be found like this.
291:3x 97
978:2x 3x 163
985:5x 197
266:2x 7x 19
776:2x 2x 2x 97
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 3x 97 = 1164
Therefore, the value for common factors is 1164.
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 = 57864397056480/(1x1164)
LCM = 57864397056480/1164
LCM = 49711681320
Thus, we can understand that the LCM of 291,978,985,266,776 is 49711681320.
