HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 122, 675 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 811, 122, 675 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 811, 122, 675 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 811, 122, 675 is 1.

HCF(811, 122, 675) = 1

Highest common factor (HCF) of 811, 122, 675 is 1.

Highest Common Factor of 811,122,675 using Euclid's algorithm

Highest Common Factor of 811,122,675 is 1

Step 1: Since 811 > 122, we apply the division lemma to 811 and 122, to get

811 = 122 x 6 + 79

Step 2: Since the reminder 122 ≠ 0, we apply division lemma to 79 and 122, to get

122 = 79 x 1 + 43

Step 3: We consider the new divisor 79 and the new remainder 43, and apply the division lemma to get

79 = 43 x 1 + 36

We consider the new divisor 43 and the new remainder 36,and apply the division lemma to get

43 = 36 x 1 + 7

We consider the new divisor 36 and the new remainder 7,and apply the division lemma to get

36 = 7 x 5 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 811 and 122 is 1

Notice that 1 = HCF(7,1) = HCF(36,7) = HCF(43,36) = HCF(79,43) = HCF(122,79) = HCF(811,122) .

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

Step 1: Since 675 > 1, we apply the division lemma to 675 and 1, to get

675 = 1 x 675 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 675 is 1

Notice that 1 = HCF(675,1) .
