How to Find LCD of 470,825,277 ?

Given numbers are 470,825,277

We can find the LCD of numbers 470,825,277 by the prime factorization method or by applying the LCD formula.

The LCD of 470,825,277 is 21481350.

Method to Find Least Common Denominator of 470,825,277 with Prime Factorization

5	470, 825, 277
	94, 165, 277

As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
5 x 94 x 165 x 277 = 21481350

Thus, we have determined that the LCD of 470,825,277 is 21481350

LCD Formula to Find LCD of 470,825,277

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

Step1:

Find the GCF of 470 and 825. To find the GCF, list down the factors of 470 and 825 and select the highest factor that appears in both lists of factors.

470 : [1, 2, 5, 10, 47, 94, 235, 470]

825 : [1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825]

From this, we can see that the GCF of 470 and 825 is 5.

Now, put this into the LCD formula.

LCD(470, 825) = ( 470 x 825 ) / 5

LCD(470, 825) = 387750 / 5

LCD(470, 825) = 77550

Step2:

Find the GCF of 77550 and 277. To find the GCF, list down the factors of 77550 and 277 and select the highest factor that appears in both lists of factors.

77550 : [1, 2, 3, 5, 6, 10, 11, 15, 22, 25, 30, 33, 47, 50, 55, 66, 75, 94, 110, 141, 150, 165, 235, 275, 282, 330, 470, 517, 550, 705, 825, 1034, 1175, 1410, 1551, 1650, 2350, 2585, 3102, 3525, 5170, 7050, 7755, 12925, 15510, 25850, 38775, 77550]

277 : [1, 277]

From this, we can see that the GCF of 77550 and 277 is 1.

Now, put this into the LCD formula.

LCD(77550, 277) = ( 77550 x 277 ) / 1

LCD(77550, 277) = 21481350 / 1

LCD(77550, 277) = 21481350

LCD of 470,825,277 is 21481350
