HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 798, 426, 998 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 798, 426, 998 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 798, 426, 998 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, 426, 998 is 2.
HCF(798, 426, 998) = 2
HCF of 798, 426, 998 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, 426, 998 is 2.
Highest Common Factor of 798,426,998 is 2
Step 1: Since 798 > 426, we apply the division lemma to 798 and 426, to get
798 = 426 x 1 + 372
Step 2: Since the reminder 426 ≠ 0, we apply division lemma to 372 and 426, to get
426 = 372 x 1 + 54
Step 3: We consider the new divisor 372 and the new remainder 54, and apply the division lemma to get
372 = 54 x 6 + 48
We consider the new divisor 54 and the new remainder 48,and apply the division lemma to get
54 = 48 x 1 + 6
We consider the new divisor 48 and the new remainder 6,and apply the division lemma to get
48 = 6 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 798 and 426 is 6
Notice that 6 = HCF(48,6) = HCF(54,48) = HCF(372,54) = HCF(426,372) = HCF(798,426) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 998 > 6, we apply the division lemma to 998 and 6, to get
998 = 6 x 166 + 2
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 2 and 6, 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 6 and 998 is 2
Notice that 2 = HCF(6,2) = HCF(998,6) .
