HCF of 63, 42 by Euclid's Divison lemma method can be determined easily by using our free online HCF using Euclid's Divison Lemma Calculator and get the result in a fraction of seconds ie., 21 the largest factor that exactly divides the numbers with r=0.
Highest common factor (HCF) of 63, 42 is 21.
HCF(63, 42) = 21
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
Below detailed show work will make you learn how to find HCF of 63,42 using the Euclidean division algorithm. So, follow the step by step explanation & check the answer for HCF(63,42).
Here 63 is greater than 42
Now, consider the largest number as 'a' from the given number ie., 63 and 42 satisfy Euclid's division lemma statement a = bq + r where 0 ≤ r < b
Step 1: Since 63 > 42, we apply the division lemma to 63 and 42, to get
63 = 42 x 1 + 21
Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 21 and 42, to get
42 = 21 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 63 and 42 is 21
Notice that 21 = HCF(42,21) = HCF(63,42) .
Therefore, HCF of 63,42 using Euclid's division lemma is 21.
1. What is the HCF(63, 42)?
The Highest common factor of 63, 42 is 21 the largest common factor that exactly divides two or more numbers with remainder 0.
2. How do you find HCF of 63, 42 using the Euclidean division algorithm?
