HCF of 77, 99 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., 11 the largest factor that exactly divides the numbers with r=0.
Highest common factor (HCF) of 77, 99 is 11.
HCF(77, 99) = 11
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 77,99 using the Euclidean division algorithm. So, follow the step by step explanation & check the answer for HCF(77,99).
Here 99 is greater than 77
Now, consider the largest number as 'a' from the given number ie., 99 and 77 satisfy Euclid's division lemma statement a = bq + r where 0 ≤ r < b
Step 1: Since 99 > 77, we apply the division lemma to 99 and 77, to get
99 = 77 x 1 + 22
Step 2: Since the reminder 77 ≠ 0, we apply division lemma to 22 and 77, to get
77 = 22 x 3 + 11
Step 3: We consider the new divisor 22 and the new remainder 11, and apply the division lemma to get
22 = 11 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 77 and 99 is 11
Notice that 11 = HCF(22,11) = HCF(77,22) = HCF(99,77) .
Therefore, HCF of 77,99 using Euclid's division lemma is 11.
1. What is the HCF(77, 99)?
