HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 633, 472, 261 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 633, 472, 261 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 633, 472, 261 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 633, 472, 261 is 1.

HCF(633, 472, 261) = 1

Highest common factor (HCF) of 633, 472, 261 is 1.

Highest Common Factor of 633,472,261 using Euclid's algorithm

Highest Common Factor of 633,472,261 is 1

Step 1: Since 633 > 472, we apply the division lemma to 633 and 472, to get

633 = 472 x 1 + 161

Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 161 and 472, to get

472 = 161 x 2 + 150

Step 3: We consider the new divisor 161 and the new remainder 150, and apply the division lemma to get

161 = 150 x 1 + 11

We consider the new divisor 150 and the new remainder 11,and apply the division lemma to get

150 = 11 x 13 + 7

We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get

11 = 7 x 1 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 633 and 472 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(150,11) = HCF(161,150) = HCF(472,161) = HCF(633,472) .

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

Step 1: Since 261 > 1, we apply the division lemma to 261 and 1, to get

261 = 1 x 261 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 261 is 1

Notice that 1 = HCF(261,1) .
