HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 498, 820, 484 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 498, 820, 484 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 498, 820, 484 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 498, 820, 484 is 2.
HCF(498, 820, 484) = 2
HCF of 498, 820, 484 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 498, 820, 484 is 2.
Highest Common Factor of 498,820,484 is 2
Step 1: Since 820 > 498, we apply the division lemma to 820 and 498, to get
820 = 498 x 1 + 322
Step 2: Since the reminder 498 ≠ 0, we apply division lemma to 322 and 498, to get
498 = 322 x 1 + 176
Step 3: We consider the new divisor 322 and the new remainder 176, and apply the division lemma to get
322 = 176 x 1 + 146
We consider the new divisor 176 and the new remainder 146,and apply the division lemma to get
176 = 146 x 1 + 30
We consider the new divisor 146 and the new remainder 30,and apply the division lemma to get
146 = 30 x 4 + 26
We consider the new divisor 30 and the new remainder 26,and apply the division lemma to get
30 = 26 x 1 + 4
We consider the new divisor 26 and the new remainder 4,and apply the division lemma to get
26 = 4 x 6 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 498 and 820 is 2
Notice that 2 = HCF(4,2) = HCF(26,4) = HCF(30,26) = HCF(146,30) = HCF(176,146) = HCF(322,176) = HCF(498,322) = HCF(820,498) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 484 > 2, we apply the division lemma to 484 and 2, to get
484 = 2 x 242 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 484 is 2
Notice that 2 = HCF(484,2) .
