HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 820, 534 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 651, 820, 534 is 1 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 651, 820, 534 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 651, 820, 534 is 1.

HCF(651, 820, 534) = 1

Highest common factor (HCF) of 651, 820, 534 is 1.

Highest Common Factor of 651,820,534 using Euclid's algorithm

Highest Common Factor of 651,820,534 is 1

Step 1: Since 820 > 651, we apply the division lemma to 820 and 651, to get

820 = 651 x 1 + 169

Step 2: Since the reminder 651 ≠ 0, we apply division lemma to 169 and 651, to get

651 = 169 x 3 + 144

Step 3: We consider the new divisor 169 and the new remainder 144, and apply the division lemma to get

169 = 144 x 1 + 25

We consider the new divisor 144 and the new remainder 25,and apply the division lemma to get

144 = 25 x 5 + 19

We consider the new divisor 25 and the new remainder 19,and apply the division lemma to get

25 = 19 x 1 + 6

We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get

19 = 6 x 3 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 651 and 820 is 1

Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(25,19) = HCF(144,25) = HCF(169,144) = HCF(651,169) = HCF(820,651) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 534 > 1, we apply the division lemma to 534 and 1, to get

534 = 1 x 534 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 534 is 1

Notice that 1 = HCF(534,1) .
