HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 261, 662 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 261, 662 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 261, 662 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 261, 662 is 1.
HCF(261, 662) = 1
HCF of 261, 662 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 261, 662 is 1.
Highest Common Factor of 261,662 is 1
Step 1: Since 662 > 261, we apply the division lemma to 662 and 261, to get
662 = 261 x 2 + 140
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 140 and 261, to get
261 = 140 x 1 + 121
Step 3: We consider the new divisor 140 and the new remainder 121, and apply the division lemma to get
140 = 121 x 1 + 19
We consider the new divisor 121 and the new remainder 19,and apply the division lemma to get
121 = 19 x 6 + 7
We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get
19 = 7 x 2 + 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 261 and 662 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(121,19) = HCF(140,121) = HCF(261,140) = HCF(662,261) .
