HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 984, 381, 261 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 984, 381, 261 is 3 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 984, 381, 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 984, 381, 261 is 3.

HCF(984, 381, 261) = 3

Highest common factor (HCF) of 984, 381, 261 is 3.

Highest Common Factor of 984,381,261 using Euclid's algorithm

Highest Common Factor of 984,381,261 is 3

Step 1: Since 984 > 381, we apply the division lemma to 984 and 381, to get

984 = 381 x 2 + 222

Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 222 and 381, to get

381 = 222 x 1 + 159

Step 3: We consider the new divisor 222 and the new remainder 159, and apply the division lemma to get

222 = 159 x 1 + 63

We consider the new divisor 159 and the new remainder 63,and apply the division lemma to get

159 = 63 x 2 + 33

We consider the new divisor 63 and the new remainder 33,and apply the division lemma to get

63 = 33 x 1 + 30

We consider the new divisor 33 and the new remainder 30,and apply the division lemma to get

33 = 30 x 1 + 3

We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get

30 = 3 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 984 and 381 is 3

Notice that 3 = HCF(30,3) = HCF(33,30) = HCF(63,33) = HCF(159,63) = HCF(222,159) = HCF(381,222) = HCF(984,381) .

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

Step 1: Since 261 > 3, we apply the division lemma to 261 and 3, to get

261 = 3 x 87 + 0

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

Notice that 3 = HCF(261,3) .
