HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 683, 939 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 683, 939 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 683, 939 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 683, 939 is 1.
HCF(683, 939) = 1
HCF of 683, 939 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 683, 939 is 1.
Highest Common Factor of 683,939 is 1
Step 1: Since 939 > 683, we apply the division lemma to 939 and 683, to get
939 = 683 x 1 + 256
Step 2: Since the reminder 683 ≠ 0, we apply division lemma to 256 and 683, to get
683 = 256 x 2 + 171
Step 3: We consider the new divisor 256 and the new remainder 171, and apply the division lemma to get
256 = 171 x 1 + 85
We consider the new divisor 171 and the new remainder 85,and apply the division lemma to get
171 = 85 x 2 + 1
We consider the new divisor 85 and the new remainder 1,and apply the division lemma to get
85 = 1 x 85 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 683 and 939 is 1
Notice that 1 = HCF(85,1) = HCF(171,85) = HCF(256,171) = HCF(683,256) = HCF(939,683) .
