Make use of LCD Calculator to determine the Least Common Denominator of 65, 28, 86 i.e. 78260 smallest integer divisible by all numbers.
LCD of 65, 28, 86 is 78260
LCD(65, 28, 86) = 78260
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
LCD of numbers 65, 28, 86 is 78260
LCD(65, 28, 86) = 78260
Arrange the Inputs 65,28,86 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 | 65, 28, 86 |
65, 14, 43 |
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 65 x 14 x 43 = 78260
Therefore, LCD of 65,28,86 is 78260
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(65, 28) = 1
LCD(65, 28) = ( 65 x 28 ) / 1
LCD(65, 28) = 1820 / 1
LCD(65, 28) = 1820
Step2:
Here we consider the LCD from the above i.e. 1820 as first number and the next as 86
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(1820, 86) = 2
LCD(1820, 86) = ( 1820 x 86 ) / 2
LCD(1820, 86) = 156520 / 2
LCD(1820, 86) = 78260
LCD of 65,28,86 is 78260
