HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 228, 382, 686 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 228, 382, 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 228, 382, 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 228, 382, 686 is 2.
HCF(228, 382, 686) = 2
HCF of 228, 382, 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 228, 382, 686 is 2.
Highest Common Factor of 228,382,686 is 2
Step 1: Since 382 > 228, we apply the division lemma to 382 and 228, to get
382 = 228 x 1 + 154
Step 2: Since the reminder 228 ≠ 0, we apply division lemma to 154 and 228, to get
228 = 154 x 1 + 74
Step 3: We consider the new divisor 154 and the new remainder 74, and apply the division lemma to get
154 = 74 x 2 + 6
We consider the new divisor 74 and the new remainder 6,and apply the division lemma to get
74 = 6 x 12 + 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 228 and 382 is 2
Notice that 2 = HCF(6,2) = HCF(74,6) = HCF(154,74) = HCF(228,154) = HCF(382,228) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 686 > 2, we apply the division lemma to 686 and 2, to get
686 = 2 x 343 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 686 is 2
Notice that 2 = HCF(686,2) .
