Make use of LCD Calculator to determine the Least Common Denominator of 155, 420, 414 i.e. 898380 smallest integer divisible by all numbers.
LCD of 155, 420, 414 is 898380
LCD(155, 420, 414) = 898380
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
LCD of numbers 155, 420, 414 is 898380
LCD(155, 420, 414) = 898380
Arrange the Inputs 155,420,414 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 | 155, 420, 414 |
3 | 155, 210, 207 |
5 | 155, 70, 69 |
31, 14, 69 |
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 31 x 14 x 69 = 898380
Therefore, LCD of 155,420,414 is 898380
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(155, 420) = 5
LCD(155, 420) = ( 155 x 420 ) / 5
LCD(155, 420) = 65100 / 5
LCD(155, 420) = 13020
Step2:
Here we consider the LCD from the above i.e. 13020 as first number and the next as 414
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(13020, 414) = 6
LCD(13020, 414) = ( 13020 x 414 ) / 6
LCD(13020, 414) = 5390280 / 6
LCD(13020, 414) = 898380
LCD of 155,420,414 is 898380
