HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 261, 669, 532 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 261, 669, 532 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 261, 669, 532 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 261, 669, 532 is 1.

HCF(261, 669, 532) = 1

Highest Common Factor of 261,669,532 using Euclid's algorithm

Highest Common Factor of 261,669,532 is 1

Step 1: Since 669 > 261, we apply the division lemma to 669 and 261, to get

669 = 261 x 2 + 147

Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 147 and 261, to get

261 = 147 x 1 + 114

Step 3: We consider the new divisor 147 and the new remainder 114, and apply the division lemma to get

147 = 114 x 1 + 33

We consider the new divisor 114 and the new remainder 33,and apply the division lemma to get

114 = 33 x 3 + 15

We consider the new divisor 33 and the new remainder 15,and apply the division lemma to get

33 = 15 x 2 + 3

We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get

15 = 3 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 261 and 669 is 3

Notice that 3 = HCF(15,3) = HCF(33,15) = HCF(114,33) = HCF(147,114) = HCF(261,147) = HCF(669,261) .

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

Step 1: Since 532 > 3, we apply the division lemma to 532 and 3, to get

532 = 3 x 177 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 532 is 1

Notice that 1 = HCF(3,1) = HCF(532,3) .
