HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 623, 263 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 623, 263 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 623, 263 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 623, 263 is 1.
HCF(623, 263) = 1
HCF of 623, 263 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 623, 263 is 1.
Highest Common Factor of 623,263 is 1
Step 1: Since 623 > 263, we apply the division lemma to 623 and 263, to get
623 = 263 x 2 + 97
Step 2: Since the reminder 263 ≠ 0, we apply division lemma to 97 and 263, to get
263 = 97 x 2 + 69
Step 3: We consider the new divisor 97 and the new remainder 69, and apply the division lemma to get
97 = 69 x 1 + 28
We consider the new divisor 69 and the new remainder 28,and apply the division lemma to get
69 = 28 x 2 + 13
We consider the new divisor 28 and the new remainder 13,and apply the division lemma to get
28 = 13 x 2 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 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 623 and 263 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(28,13) = HCF(69,28) = HCF(97,69) = HCF(263,97) = HCF(623,263) .
