HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 939, 891 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 939, 891 is 3 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 939, 891 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 939, 891 is 3.
HCF(939, 891) = 3
HCF of 939, 891 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 939, 891 is 3.
Highest Common Factor of 939,891 is 3
Step 1: Since 939 > 891, we apply the division lemma to 939 and 891, to get
939 = 891 x 1 + 48
Step 2: Since the reminder 891 ≠ 0, we apply division lemma to 48 and 891, to get
891 = 48 x 18 + 27
Step 3: We consider the new divisor 48 and the new remainder 27, and apply the division lemma to get
48 = 27 x 1 + 21
We consider the new divisor 27 and the new remainder 21,and apply the division lemma to get
27 = 21 x 1 + 6
We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get
21 = 6 x 3 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 939 and 891 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(27,21) = HCF(48,27) = HCF(891,48) = HCF(939,891) .
