HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 304, 686 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 304, 686 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 304, 686 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 304, 686 is 2.
HCF(304, 686) = 2
HCF of 304, 686 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 304, 686 is 2.
Highest Common Factor of 304,686 is 2
Step 1: Since 686 > 304, we apply the division lemma to 686 and 304, to get
686 = 304 x 2 + 78
Step 2: Since the reminder 304 ≠ 0, we apply division lemma to 78 and 304, to get
304 = 78 x 3 + 70
Step 3: We consider the new divisor 78 and the new remainder 70, and apply the division lemma to get
78 = 70 x 1 + 8
We consider the new divisor 70 and the new remainder 8,and apply the division lemma to get
70 = 8 x 8 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 304 and 686 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(70,8) = HCF(78,70) = HCF(304,78) = HCF(686,304) .
