HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 420, 5196 i.e. 12 the largest integer that leaves a remainder zero for all numbers.
HCF of 420, 5196 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 420, 5196 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 420, 5196 is 12.
HCF(420, 5196) = 12
HCF of 420, 5196 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 420, 5196 is 12.
Highest Common Factor of 420,5196 is 12
Step 1: Since 5196 > 420, we apply the division lemma to 5196 and 420, to get
5196 = 420 x 12 + 156
Step 2: Since the reminder 420 ≠ 0, we apply division lemma to 156 and 420, to get
420 = 156 x 2 + 108
Step 3: We consider the new divisor 156 and the new remainder 108, and apply the division lemma to get
156 = 108 x 1 + 48
We consider the new divisor 108 and the new remainder 48,and apply the division lemma to get
108 = 48 x 2 + 12
We consider the new divisor 48 and the new remainder 12,and apply the division lemma to get
48 = 12 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 420 and 5196 is 12
Notice that 12 = HCF(48,12) = HCF(108,48) = HCF(156,108) = HCF(420,156) = HCF(5196,420) .
