HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 682 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 388, 682 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 388, 682 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 388, 682 is 2.
HCF(388, 682) = 2
HCF of 388, 682 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 388, 682 is 2.
Highest Common Factor of 388,682 is 2
Step 1: Since 682 > 388, we apply the division lemma to 682 and 388, to get
682 = 388 x 1 + 294
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 294 and 388, to get
388 = 294 x 1 + 94
Step 3: We consider the new divisor 294 and the new remainder 94, and apply the division lemma to get
294 = 94 x 3 + 12
We consider the new divisor 94 and the new remainder 12,and apply the division lemma to get
94 = 12 x 7 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 388 and 682 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(94,12) = HCF(294,94) = HCF(388,294) = HCF(682,388) .
