HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 244, 79478 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 244, 79478 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 244, 79478 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 244, 79478 is 2.
HCF(244, 79478) = 2
HCF of 244, 79478 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 244, 79478 is 2.
Highest Common Factor of 244,79478 is 2
Step 1: Since 79478 > 244, we apply the division lemma to 79478 and 244, to get
79478 = 244 x 325 + 178
Step 2: Since the reminder 244 ≠ 0, we apply division lemma to 178 and 244, to get
244 = 178 x 1 + 66
Step 3: We consider the new divisor 178 and the new remainder 66, and apply the division lemma to get
178 = 66 x 2 + 46
We consider the new divisor 66 and the new remainder 46,and apply the division lemma to get
66 = 46 x 1 + 20
We consider the new divisor 46 and the new remainder 20,and apply the division lemma to get
46 = 20 x 2 + 6
We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get
20 = 6 x 3 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 244 and 79478 is 2
Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(46,20) = HCF(66,46) = HCF(178,66) = HCF(244,178) = HCF(79478,244) .
