HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 798, 498 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 798, 498 is 6 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 798, 498 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 798, 498 is 6.
HCF(798, 498) = 6
HCF of 798, 498 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 798, 498 is 6.
Highest Common Factor of 798,498 is 6
Step 1: Since 798 > 498, we apply the division lemma to 798 and 498, to get
798 = 498 x 1 + 300
Step 2: Since the reminder 498 ≠ 0, we apply division lemma to 300 and 498, to get
498 = 300 x 1 + 198
Step 3: We consider the new divisor 300 and the new remainder 198, and apply the division lemma to get
300 = 198 x 1 + 102
We consider the new divisor 198 and the new remainder 102,and apply the division lemma to get
198 = 102 x 1 + 96
We consider the new divisor 102 and the new remainder 96,and apply the division lemma to get
102 = 96 x 1 + 6
We consider the new divisor 96 and the new remainder 6,and apply the division lemma to get
96 = 6 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 798 and 498 is 6
Notice that 6 = HCF(96,6) = HCF(102,96) = HCF(198,102) = HCF(300,198) = HCF(498,300) = HCF(798,498) .
