HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 538, 562 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 538, 562 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 820, 538, 562 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 820, 538, 562 is 2.
HCF(820, 538, 562) = 2
HCF of 820, 538, 562 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 538, 562 is 2.
Highest Common Factor of 820,538,562 is 2
Step 1: Since 820 > 538, we apply the division lemma to 820 and 538, to get
820 = 538 x 1 + 282
Step 2: Since the reminder 538 ≠ 0, we apply division lemma to 282 and 538, to get
538 = 282 x 1 + 256
Step 3: We consider the new divisor 282 and the new remainder 256, and apply the division lemma to get
282 = 256 x 1 + 26
We consider the new divisor 256 and the new remainder 26,and apply the division lemma to get
256 = 26 x 9 + 22
We consider the new divisor 26 and the new remainder 22,and apply the division lemma to get
26 = 22 x 1 + 4
We consider the new divisor 22 and the new remainder 4,and apply the division lemma to get
22 = 4 x 5 + 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 820 and 538 is 2
Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(26,22) = HCF(256,26) = HCF(282,256) = HCF(538,282) = HCF(820,538) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 562 > 2, we apply the division lemma to 562 and 2, to get
562 = 2 x 281 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 562 is 2
Notice that 2 = HCF(562,2) .
