HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1368, 6643 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1368, 6643 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 1368, 6643 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 1368, 6643 is 1.
HCF(1368, 6643) = 1
HCF of 1368, 6643 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1368, 6643 is 1.
Highest Common Factor of 1368,6643 is 1
Step 1: Since 6643 > 1368, we apply the division lemma to 6643 and 1368, to get
6643 = 1368 x 4 + 1171
Step 2: Since the reminder 1368 ≠ 0, we apply division lemma to 1171 and 1368, to get
1368 = 1171 x 1 + 197
Step 3: We consider the new divisor 1171 and the new remainder 197, and apply the division lemma to get
1171 = 197 x 5 + 186
We consider the new divisor 197 and the new remainder 186,and apply the division lemma to get
197 = 186 x 1 + 11
We consider the new divisor 186 and the new remainder 11,and apply the division lemma to get
186 = 11 x 16 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1368 and 6643 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(186,11) = HCF(197,186) = HCF(1171,197) = HCF(1368,1171) = HCF(6643,1368) .
