How to Find LCD of 908,945,146 ?

Given numbers are 908,945,146

We can find the LCD of numbers 908,945,146 by the prime factorization method or by applying the LCD formula.

The LCD of 908,945,146 is 62638380.

Method to Find Least Common Denominator of 908,945,146 with Prime Factorization

2	908, 945, 146
	454, 945, 73

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 454 x 945 x 73 = 62638380

Thus, we have determined that the LCD of 908,945,146 is 62638380

LCD Formula to Find LCD of 908,945,146

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

Step1:

Find the GCF of 908 and 945. To find the GCF, list down the factors of 908 and 945 and select the highest factor that appears in both lists of factors.

908 : [1, 2, 4, 227, 454, 908]

945 : [1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945]

From this, we can see that the GCF of 908 and 945 is 1.

Now, put this into the LCD formula.

LCD(908, 945) = ( 908 x 945 ) / 1

LCD(908, 945) = 858060 / 1

LCD(908, 945) = 858060

Step2:

Find the GCF of 858060 and 146. To find the GCF, list down the factors of 858060 and 146 and select the highest factor that appears in both lists of factors.

858060 : [1, 2, 3, 4, 5, 6, 7, 9, 10, 12, 14, 15, 18, 20, 21, 27, 28, 30, 35, 36, 42, 45, 54, 60, 63, 70, 84, 90, 105, 108, 126, 135, 140, 180, 189, 210, 227, 252, 270, 315, 378, 420, 454, 540, 630, 681, 756, 908, 945, 1135, 1260, 1362, 1589, 1890, 2043, 2270, 2724, 3178, 3405, 3780, 4086, 4540, 4767, 6129, 6356, 6810, 7945, 8172, 9534, 10215, 12258, 13620, 14301, 15890, 19068, 20430, 23835, 24516, 28602, 30645, 31780, 40860, 42903, 47670, 57204, 61290, 71505, 85806, 95340, 122580, 143010, 171612, 214515, 286020, 429030, 858060]

146 : [1, 2, 73, 146]

From this, we can see that the GCF of 858060 and 146 is 2.

Now, put this into the LCD formula.

LCD(858060, 146) = ( 858060 x 146 ) / 2

LCD(858060, 146) = 125276760 / 2

LCD(858060, 146) = 62638380

LCD of 908,945,146 is 62638380
