HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 324, 492 i.e. 12 the largest integer that leaves a remainder zero for all numbers.
HCF of 324, 492 is 12 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 324, 492 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 324, 492 is 12.
HCF(324, 492) = 12
HCF of 324, 492 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 324, 492 is 12.
Highest Common Factor of 324,492 is 12
Step 1: Since 492 > 324, we apply the division lemma to 492 and 324, to get
492 = 324 x 1 + 168
Step 2: Since the reminder 324 ≠ 0, we apply division lemma to 168 and 324, to get
324 = 168 x 1 + 156
Step 3: We consider the new divisor 168 and the new remainder 156, and apply the division lemma to get
168 = 156 x 1 + 12
We consider the new divisor 156 and the new remainder 12, and apply the division lemma to get
156 = 12 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 324 and 492 is 12
Notice that 12 = HCF(156,12) = HCF(168,156) = HCF(324,168) = HCF(492,324) .
