Make use of LCD Calculator to determine the Least Common Denominator of 441, 686, 755 i.e. 4661370 smallest integer divisible by all numbers.
LCD of 441, 686, 755 is 4661370
LCD(441, 686, 755) = 4661370
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
LCD of numbers 441, 686, 755 is 4661370
LCD(441, 686, 755) = 4661370
Arrange the Inputs 441,686,755 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.
7 | 441, 686, 755 |
7 | 63, 98, 755 |
9, 14, 755 |
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. 7 x 7 x 9 x 14 x 755 = 4661370
Therefore, LCD of 441,686,755 is 4661370
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(441, 686) = 49
LCD(441, 686) = ( 441 x 686 ) / 49
LCD(441, 686) = 302526 / 49
LCD(441, 686) = 6174
Step2:
Here we consider the LCD from the above i.e. 6174 as first number and the next as 755
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(6174, 755) = 1
LCD(6174, 755) = ( 6174 x 755 ) / 1
LCD(6174, 755) = 4661370 / 1
LCD(6174, 755) = 4661370
LCD of 441,686,755 is 4661370
