HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 420, 382 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 420, 382 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 420, 382 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, 382 is 2.
HCF(420, 382) = 2
HCF of 420, 382 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, 382 is 2.
Highest Common Factor of 420,382 is 2
Step 1: Since 420 > 382, we apply the division lemma to 420 and 382, to get
420 = 382 x 1 + 38
Step 2: Since the reminder 382 ≠ 0, we apply division lemma to 38 and 382, to get
382 = 38 x 10 + 2
Step 3: We consider the new divisor 38 and the new remainder 2, and apply the division lemma to get
38 = 2 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 420 and 382 is 2
Notice that 2 = HCF(38,2) = HCF(382,38) = HCF(420,382) .
