HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 286, 620, 82 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 286, 620, 82 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 286, 620, 82 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 286, 620, 82 is 2.
HCF(286, 620, 82) = 2
HCF of 286, 620, 82 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 286, 620, 82 is 2.
Highest Common Factor of 286,620,82 is 2
Step 1: Since 620 > 286, we apply the division lemma to 620 and 286, to get
620 = 286 x 2 + 48
Step 2: Since the reminder 286 ≠ 0, we apply division lemma to 48 and 286, to get
286 = 48 x 5 + 46
Step 3: We consider the new divisor 48 and the new remainder 46, and apply the division lemma to get
48 = 46 x 1 + 2
We consider the new divisor 46 and the new remainder 2, and apply the division lemma to get
46 = 2 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 286 and 620 is 2
Notice that 2 = HCF(46,2) = HCF(48,46) = HCF(286,48) = HCF(620,286) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 82 > 2, we apply the division lemma to 82 and 2, to get
82 = 2 x 41 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 82 is 2
Notice that 2 = HCF(82,2) .
