HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 905, 533, 97 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 905, 533, 97 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 905, 533, 97 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 905, 533, 97 is 1.

HCF(905, 533, 97) = 1

Highest common factor (HCF) of 905, 533, 97 is 1.

Highest Common Factor of 905,533,97 using Euclid's algorithm

Highest Common Factor of 905,533,97 is 1

Step 1: Since 905 > 533, we apply the division lemma to 905 and 533, to get

905 = 533 x 1 + 372

Step 2: Since the reminder 533 ≠ 0, we apply division lemma to 372 and 533, to get

533 = 372 x 1 + 161

Step 3: We consider the new divisor 372 and the new remainder 161, and apply the division lemma to get

372 = 161 x 2 + 50

We consider the new divisor 161 and the new remainder 50,and apply the division lemma to get

161 = 50 x 3 + 11

We consider the new divisor 50 and the new remainder 11,and apply the division lemma to get

50 = 11 x 4 + 6

We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get

11 = 6 x 1 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 905 and 533 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(50,11) = HCF(161,50) = HCF(372,161) = HCF(533,372) = HCF(905,533) .

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

Step 1: Since 97 > 1, we apply the division lemma to 97 and 1, to get

97 = 1 x 97 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 97 is 1

Notice that 1 = HCF(97,1) .
