HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 686, 5102 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 686, 5102 is 2 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 686, 5102 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 686, 5102 is 2.
HCF(686, 5102) = 2
HCF of 686, 5102 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 686, 5102 is 2.
Highest Common Factor of 686,5102 is 2
Step 1: Since 5102 > 686, we apply the division lemma to 5102 and 686, to get
5102 = 686 x 7 + 300
Step 2: Since the reminder 686 ≠ 0, we apply division lemma to 300 and 686, to get
686 = 300 x 2 + 86
Step 3: We consider the new divisor 300 and the new remainder 86, and apply the division lemma to get
300 = 86 x 3 + 42
We consider the new divisor 86 and the new remainder 42,and apply the division lemma to get
86 = 42 x 2 + 2
We consider the new divisor 42 and the new remainder 2,and apply the division lemma to get
42 = 2 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 686 and 5102 is 2
Notice that 2 = HCF(42,2) = HCF(86,42) = HCF(300,86) = HCF(686,300) = HCF(5102,686) .
