HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 420, 92 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 420, 92 is 4 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, 92 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, 92 is 4.
HCF(420, 92) = 4
HCF of 420, 92 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, 92 is 4.
Highest Common Factor of 420,92 is 4
Step 1: Since 420 > 92, we apply the division lemma to 420 and 92, to get
420 = 92 x 4 + 52
Step 2: Since the reminder 92 ≠ 0, we apply division lemma to 52 and 92, to get
92 = 52 x 1 + 40
Step 3: We consider the new divisor 52 and the new remainder 40, and apply the division lemma to get
52 = 40 x 1 + 12
We consider the new divisor 40 and the new remainder 12,and apply the division lemma to get
40 = 12 x 3 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 420 and 92 is 4
Notice that 4 = HCF(12,4) = HCF(40,12) = HCF(52,40) = HCF(92,52) = HCF(420,92) .
