HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 841, 693 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 841, 693 is 1 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 841, 693 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 841, 693 is 1.
HCF(841, 693) = 1
HCF of 841, 693 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 841, 693 is 1.
Highest Common Factor of 841,693 is 1
Step 1: Since 841 > 693, we apply the division lemma to 841 and 693, to get
841 = 693 x 1 + 148
Step 2: Since the reminder 693 ≠ 0, we apply division lemma to 148 and 693, to get
693 = 148 x 4 + 101
Step 3: We consider the new divisor 148 and the new remainder 101, and apply the division lemma to get
148 = 101 x 1 + 47
We consider the new divisor 101 and the new remainder 47,and apply the division lemma to get
101 = 47 x 2 + 7
We consider the new divisor 47 and the new remainder 7,and apply the division lemma to get
47 = 7 x 6 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 841 and 693 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(47,7) = HCF(101,47) = HCF(148,101) = HCF(693,148) = HCF(841,693) .
