HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 492, 339 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 492, 339 is 3 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 492, 339 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 492, 339 is 3.
HCF(492, 339) = 3
HCF of 492, 339 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 492, 339 is 3.
Highest Common Factor of 492,339 is 3
Step 1: Since 492 > 339, we apply the division lemma to 492 and 339, to get
492 = 339 x 1 + 153
Step 2: Since the reminder 339 ≠ 0, we apply division lemma to 153 and 339, to get
339 = 153 x 2 + 33
Step 3: We consider the new divisor 153 and the new remainder 33, and apply the division lemma to get
153 = 33 x 4 + 21
We consider the new divisor 33 and the new remainder 21,and apply the division lemma to get
33 = 21 x 1 + 12
We consider the new divisor 21 and the new remainder 12,and apply the division lemma to get
21 = 12 x 1 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 492 and 339 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(33,21) = HCF(153,33) = HCF(339,153) = HCF(492,339) .
