HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 656, 19996 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 656, 19996 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 656, 19996 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 656, 19996 is 4.
HCF(656, 19996) = 4
HCF of 656, 19996 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 656, 19996 is 4.
Highest Common Factor of 656,19996 is 4
Step 1: Since 19996 > 656, we apply the division lemma to 19996 and 656, to get
19996 = 656 x 30 + 316
Step 2: Since the reminder 656 ≠ 0, we apply division lemma to 316 and 656, to get
656 = 316 x 2 + 24
Step 3: We consider the new divisor 316 and the new remainder 24, and apply the division lemma to get
316 = 24 x 13 + 4
We consider the new divisor 24 and the new remainder 4, and apply the division lemma to get
24 = 4 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 656 and 19996 is 4
Notice that 4 = HCF(24,4) = HCF(316,24) = HCF(656,316) = HCF(19996,656) .
