Make use of LCD Calculator to determine the Least Common Denominator of 780, 330, 786 i.e. 1123980 smallest integer divisible by all numbers.
LCD of 780, 330, 786 is 1123980
LCD(780, 330, 786) = 1123980
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
LCD of numbers 780, 330, 786 is 1123980
LCD(780, 330, 786) = 1123980
Arrange the Inputs 780,330,786 in a horizontal line separated by commas and divide them with a prime number. Note the quotients in the next row and divide with quotients with prime numbers again. Continue the process until you have all co primes in the last.
2 | 780, 330, 786 |
3 | 390, 165, 393 |
5 | 130, 55, 131 |
26, 11, 131 |
As all the numbers left in the last row are co primes you need not do the common division process further.
To obtain the Least Common Denominator, multiply the prime numbers with which you have divided the given numbers and the co primes in the last row i.e. 2 x 3 x 5 x 26 x 11 x 131 = 1123980
Therefore, LCD of 780,330,786 is 1123980
Step1:
Let's calculate the LCD of first two numbers
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(780, 330) = 30
LCD(780, 330) = ( 780 x 330 ) / 30
LCD(780, 330) = 257400 / 30
LCD(780, 330) = 8580
Step2:
Here we consider the LCD from the above i.e. 8580 as first number and the next as 786
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(8580, 786) = 6
LCD(8580, 786) = ( 8580 x 786 ) / 6
LCD(8580, 786) = 6743880 / 6
LCD(8580, 786) = 1123980
LCD of 780,330,786 is 1123980
