How to Find LCD of 356,430,939 ?

Given numbers are 356,430,939

We can find the LCD of numbers 356,430,939 by the prime factorization method or by applying the LCD formula.

The LCD of 356,430,939 is 71871060.


Method to Find Least Common Denominator of 356,430,939 with Prime Factorization

2 356, 430, 939
178, 215, 939

As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
2 x 178 x 215 x 939 = 71871060

Thus, we have determined that the LCD of 356,430,939 is 71871060

LCD Formula to Find LCD of 356,430,939

The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)


Step1:

Find the GCF of 356 and 430. To find the GCF, list down the factors of 356 and 430 and select the highest factor that appears in both lists of factors.

356 : [1, 2, 4, 89, 178, 356]

430 : [1, 2, 5, 10, 43, 86, 215, 430]

From this, we can see that the GCF of 356 and 430 is 2.

Now, put this into the LCD formula.

LCD(356, 430) = ( 356 x 430 ) / 2

LCD(356, 430) = 153080 / 2

LCD(356, 430) = 76540


Step2:

Find the GCF of 76540 and 939. To find the GCF, list down the factors of 76540 and 939 and select the highest factor that appears in both lists of factors.

76540 : [1, 2, 4, 5, 10, 20, 43, 86, 89, 172, 178, 215, 356, 430, 445, 860, 890, 1780, 3827, 7654, 15308, 19135, 38270, 76540]

939 : [1, 3, 313, 939]

From this, we can see that the GCF of 76540 and 939 is 1.

Now, put this into the LCD formula.

LCD(76540, 939) = ( 76540 x 939 ) / 1

LCD(76540, 939) = 71871060 / 1

LCD(76540, 939) = 71871060

LCD of 356,430,939 is 71871060
