HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 805, 232, 151 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 805, 232, 151 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 805, 232, 151 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 805, 232, 151 is 1.

HCF(805, 232, 151) = 1

Highest common factor (HCF) of 805, 232, 151 is 1.

Highest Common Factor of 805,232,151 using Euclid's algorithm

Highest Common Factor of 805,232,151 is 1

Step 1: Since 805 > 232, we apply the division lemma to 805 and 232, to get

805 = 232 x 3 + 109

Step 2: Since the reminder 232 ≠ 0, we apply division lemma to 109 and 232, to get

232 = 109 x 2 + 14

Step 3: We consider the new divisor 109 and the new remainder 14, and apply the division lemma to get

109 = 14 x 7 + 11

We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get

14 = 11 x 1 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 805 and 232 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(109,14) = HCF(232,109) = HCF(805,232) .

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

Step 1: Since 151 > 1, we apply the division lemma to 151 and 1, to get

151 = 1 x 151 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 151 is 1

Notice that 1 = HCF(151,1) .
