HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 281, 987, 149 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 281, 987, 149 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 281, 987, 149 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 281, 987, 149 is 1.

HCF(281, 987, 149) = 1

HCF of 281, 987, 149 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 281, 987, 149 is 1.

Highest Common Factor of 281,987,149 using Euclid's algorithm

Highest Common Factor of 281,987,149 is 1

Step 1: Since 987 > 281, we apply the division lemma to 987 and 281, to get

987 = 281 x 3 + 144

Step 2: Since the reminder 281 ≠ 0, we apply division lemma to 144 and 281, to get

281 = 144 x 1 + 137

Step 3: We consider the new divisor 144 and the new remainder 137, and apply the division lemma to get

144 = 137 x 1 + 7

We consider the new divisor 137 and the new remainder 7,and apply the division lemma to get

137 = 7 x 19 + 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 281 and 987 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(137,7) = HCF(144,137) = HCF(281,144) = HCF(987,281) .

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

Step 1: Since 149 > 1, we apply the division lemma to 149 and 1, to get

149 = 1 x 149 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 149 is 1

Notice that 1 = HCF(149,1) .
