HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 865, 790 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 865, 790 is 5 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 865, 790 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 865, 790 is 5.
HCF(865, 790) = 5
HCF of 865, 790 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 865, 790 is 5.
Highest Common Factor of 865,790 is 5
Step 1: Since 865 > 790, we apply the division lemma to 865 and 790, to get
865 = 790 x 1 + 75
Step 2: Since the reminder 790 ≠ 0, we apply division lemma to 75 and 790, to get
790 = 75 x 10 + 40
Step 3: We consider the new divisor 75 and the new remainder 40, and apply the division lemma to get
75 = 40 x 1 + 35
We consider the new divisor 40 and the new remainder 35,and apply the division lemma to get
40 = 35 x 1 + 5
We consider the new divisor 35 and the new remainder 5,and apply the division lemma to get
35 = 5 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 865 and 790 is 5
Notice that 5 = HCF(35,5) = HCF(40,35) = HCF(75,40) = HCF(790,75) = HCF(865,790) .
