HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 869, 71605 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 869, 71605 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 869, 71605 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 869, 71605 is 1.
HCF(869, 71605) = 1
HCF of 869, 71605 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 869, 71605 is 1.
Highest Common Factor of 869,71605 is 1
Step 1: Since 71605 > 869, we apply the division lemma to 71605 and 869, to get
71605 = 869 x 82 + 347
Step 2: Since the reminder 869 ≠ 0, we apply division lemma to 347 and 869, to get
869 = 347 x 2 + 175
Step 3: We consider the new divisor 347 and the new remainder 175, and apply the division lemma to get
347 = 175 x 1 + 172
We consider the new divisor 175 and the new remainder 172,and apply the division lemma to get
175 = 172 x 1 + 3
We consider the new divisor 172 and the new remainder 3,and apply the division lemma to get
172 = 3 x 57 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 869 and 71605 is 1
Notice that 1 = HCF(3,1) = HCF(172,3) = HCF(175,172) = HCF(347,175) = HCF(869,347) = HCF(71605,869) .
