HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 409, 167, 173, 977 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 409, 167, 173, 977 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 409, 167, 173, 977 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 409, 167, 173, 977 is 1.

HCF(409, 167, 173, 977) = 1

Highest common factor (HCF) of 409, 167, 173, 977 is 1.

Highest Common Factor of 409,167,173,977 using Euclid's algorithm

Highest Common Factor of 409,167,173,977 is 1

Step 1: Since 409 > 167, we apply the division lemma to 409 and 167, to get

409 = 167 x 2 + 75

Step 2: Since the reminder 167 ≠ 0, we apply division lemma to 75 and 167, to get

167 = 75 x 2 + 17

Step 3: We consider the new divisor 75 and the new remainder 17, and apply the division lemma to get

75 = 17 x 4 + 7

We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get

17 = 7 x 2 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 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 409 and 167 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(75,17) = HCF(167,75) = HCF(409,167) .


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

Step 1: Since 173 > 1, we apply the division lemma to 173 and 1, to get

173 = 1 x 173 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 173 is 1

Notice that 1 = HCF(173,1) .


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

Step 1: Since 977 > 1, we apply the division lemma to 977 and 1, to get

977 = 1 x 977 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 977 is 1

Notice that 1 = HCF(977,1) .
